Identify Differences Between Package Versions

Description

The pkgdiff package contains functions to identify differences between versions of R packages. The pkgdiff package was written specifically to detect breaking changes and help with package upgrades.

Functions

The main functions included in the pkgdiff package are as follows:

pkg_info: Retrieves general information about a package, mostly from the package description file.
pkg_versions: Gets a data frame containing all versions of a package and the release date for each.
pkg_diff: Compares two package versions, and returns an object that contains the differences in terms of exported function signatures.
pkg_stability: Compiles information on package stability over time, and calculates a score based on this information. This function is useful when making package selection choices.
pkg_repo: Fetches package names and versions for packages in a specified repository.
repo_breakages: Identifies breakages when upgrading from one version of a repository to another.
repo_stability: Performs a stability assessment on multiple packages, even an entire repository.

For additional information on pkgdiff, see the package vignette vignette('pkgdiff'), or visit the package web site here.

Queries the Package Cache

Description

The pkg_cache function queries the package cache, and returns information on which packages are included in the cache. The function also returns the last version of the package cached.

Usage

pkg_cache(pkgs = NULL)

Arguments

pkgs

A vector of package names to retrieve cache information about. Default is NULL, which means to return all packages in the cache.

Details

The pkgdiff cache is used to speed up pkgdiff functions. Information about each package is pre-processed and stored in the cache on Github. The functions then retrieve this pre-processed information instead of pulling packages down from CRAN. To learn more about the cache, refer to vignette('pkgdiff-cache').

Value

An data frame showing the package name and latest package version stored in the cache. If the package is not stored in the cache, the package version will be NA. The "Last Update" time stamp is the last day and time the cache was updated.

Compare Package Versions

Description

The pkg_diff function is used to compare two different versions of a package. The function returns an object that contains the differences. Differences include any functions added or removed, and any function parameters added or removed. The object may be printed directly, or stored in a variable and examined programmatically.

Usage

pkg_diff(pkg, v1 = "current", v2 = "latest")

Arguments

pkg

The package name.

v1

The earlier package version. Pass the version value as a quoted string. Default is "current", which means the function will look up the currently installed version.

v2

The later package version. Pass the version value as a quoted string. The default is "latest", which is the latest version of the package available on CRAN.

Details

The difference operation only compares functions that are exported from the package. It does not compare internal functions or function documentation. Exported functions are identified in the package namespace.

The pkg_diff function can compare any two versions of a package. They do not need to be consecutive. They must, however, exist in the CRAN archive.

If the package versions are included in the pkgdiff cache, the function will pull them from there. Otherwise, they will be pulled from the CRAN mirror. The function does not access any packages on the local system.

Value

An object of class "pdiff", which contains information regarding the differences between two versions of a package. The object includes a list of functions that were added, a list of function parameters that were added, a list of functions removed, and a list of function parameters that were removed. The object also contains some general information like the package versions examined, and a TRUE or FALSE flag indicating whether there were any breaking changes.

Get Information for a Package

Description

Combines information related to a package. Objects of this class are used by several other functions in the pkgdiff system. This class also makes a compact storage format for pre-processed package information.

Usage

pkg_info(pkg, ver = "current", cache = TRUE)

Arguments

pkg

The package name as a quoted string. This parameter is required.

ver

The version of the package to retrieve information for. Pass the version as a quoted string. Special values are "current" and "latest". The value "current" is the current version of the package running on the machine. The value "latest" is the latest version of the package from CRAN.

cache

Whether to retrieve the info from the Github cache, or from CRAN. If TRUE, the function will first search the cache, and return the info if available. If the info is not available in the Github cache, or the cache parameter is set to FALSE, the info will be retrieved from CRAN.

Details

Package information is unique for each version of a package. Since a package can have multiple versions, you must select which version you wish to return information for. By default, the version returned is the current version of the package on the current machine. You may also specify a previous version number from the CRAN archive. Another option is to specify the latest version on CRAN. See the "ver" parameter for additional details on how to select these different package versions.

The package info object contains a list of functions and function parameters associated with the specified version of the package. You may access this list using the $Functions item name.

Most other information contained in the info object is retrieved from the package description file. One exception is the downloads per month. This information is retrieved from CRAN logs.

In addition, the package cache status is appended to the info object. The package cache status indicates whether the package info has been stored in the pkgdiff Github cache. Packages that have been stored in the cache enjoy faster results from pkgdiff functions.

Note that pkg_info and other pkgdiff functions only work with contributed CRAN packages. They do not work with Base R packages.

Value

A package information object of class "pinfo". This object contains a set of general information about the package, such as the version, release date, maintainer, title, etc. Most of this information comes from the package description file. In addition, the info object also contains a list of functions in the package and their parameters.

If the package has been archived on CRAN, info will be returned, but the "Archived" flag will be set to TRUE. If the package is not found on CRAN, the function will emit a message and return NULL.

If the package is a Base R package, a reduced number of fields will be returned, and the package will be marked with Base Package: TRUE. Function lists are not available for Base packages.

Retrieve Package Versions from a Repository

Description

The pkg_repo function combines information related to a package repository. The function retrieves all the packages in a repository for a specified version of R. Results will list the package name and version.

Usage

pkg_repo(pkgs = NULL, ver = "current", libpaths = NULL)

Arguments

pkgs

A vector of package names used to subset the repository list. Default is NULL, which means all packages in the repository will be returned.

ver

The R version of the repository. Pass the R version as a quoted string. Default is "current", meaning the current version of the repository. The value "latest" will return the latest versions on CRAN.

libpaths

A vector of paths specifying the locations of the repositories to query. Default is NULL, meaning the function will use the default R locations on the machine. These default paths are identified by the Base R function .libPaths().

Value

An object of class "prepo". The object will contain a data frame of R packages with corresponding version numbers. This table may then be passed to repo_breakages or repo_stability.

If a package is not found in the repo, a row will still be returned for the package. However, the version will appear as NA.

Examples

# Create vector of packages
pkgs <- c("common", "dplyr", "rvest", "stringr")

# Retrieve latest versions
pkg_repo(pkgs, ver = "latest")
# # A package repo object
# - Repo Version: latest
# - Packages:
#   Package Version
# 1  common   1.1.3
# 2   dplyr   1.1.4
# 3   rvest   1.0.4
# 4 stringr   1.5.1

Calculate Stability Score for a Package

Description

The pkg_stablity function calculates a stability score for a specified package. The score is calculated as the percentage of releases with no breaking changes. A breaking change is defined as either a removed function or removed function parameter. The object also returns the raw data from which the stability score is calculated. This data can be useful for review or even custom analytics.

Usage

pkg_stability(pkg, releases = NULL, months = NULL)

Arguments

pkg

The name of the package.

releases

An integer indicating the number of releases to collect stability data for. For example, releases = 10 will return stability data for the last 10 releases of the package. Default is NULL, which means the function will return data for all releases.

months

An integer indicating the number of months back to collect stability data for. For example, months = 24 will collect stability data for the previous 2 years. Default is NULL, meaning there is no limitation on the number of release months, and the function will collect data from all releases.

Details

The pkg_stability function is used to get an overall feel for the stability of a package. The stability score and other information returned by the function are based on data retrieved from CRAN. The function compares each version of a package and determines if any functions or function parameters have been removed from the previous release. If a release removes functions or parameters contained in the previous release, it is flagged as a "breaking release" or "breaking change".

The stability score is calculated as the percentage of non-breaking releases. For example, if a package has 10 releases, and one breaking release, the stability score will be .9, or 90%.

The stability assessment is a categorization of the stability score. The aim of the assessment is to provide a general evaluation of the package, whether it is stable or unstable. The assessment has 5 categories:

Perfect: Stability score of 100. Package has never had a breaking release in its entire history.
Very Stable: Stability score between 95 and 100. Package has had a breaking release, but very rarely: less than 1 in 20 releases.
Stable: Stability score between 90 and 95. The package has had some breaking releases, but it is still rather rare: less than 1 in 10 releases.
Somewhat unstable: Stability score between 80 and 90. The package sometimes has a breaking release, at a rate of about 1 in 5.
Unstable: Stability score below 80. The package breaks more frequently than every 5th release. This frequency of breaking releases is considered unstable.

As can be seen above, the stability assessment is weighted heavily toward the high end. This categorization is intentionally designed to encourage package stability, and discourage the number of breaking changes.

Value

An stability score object of class "pdiff_score". The object contains the stability score, plus other useful information such as the release and version ranges, the number of releases, and number of breaking releases. All of these items can be accessed using dollar sign ($) syntax.

Stability Data

Stability calculations are based on a data frame of stability information gathered from each package release. The data frame has one row per release. Each row contains comparison information against the prior release. The columns are organized as follows:

Package: The package name.
Version: The version number of the release.
FileName: The file name of the package.
Release: The release date of the package.
Size: The size of the package file on disk.
AF: The number of functions added from the previous release.
AP: The number of functions that had parameters added from the previous release.
RF: The number of functions removed from the previous release.
RP: The number of functions that had parameters removed from the previous release.
BC: Whether the release had any breaking changes. Breaking changes are removed functions or removed parameters. Values are zero or one. The value one (1) means the release had breaking changes. The value zero (0) means the release had no breaking changes.
TF: The total number of functions in the package.

The above data will be included in the function print out. It can also be accessed on the returned object from the "data" list item, i.e. obj$data.

Disclaimers

Note that a "breaking release" does not factor in the number of functions deprecated. One deprecated function counts the same as 10 deprecated functions within a release. The methodology also does not differentiate between removed functions and removed parameters. They are both considered "breaking", and counted equally.

The methodology also does not factor in changed functions. The reason is simply that it is much more difficult to identify whether or not a changed function is breaking. That is to say, you may still have breaking changes that are not identified by the pkgdiff package.

Performance

Performance of the pkg_stability function can vary greatly depending on the package selected. The information for some packages has been cached on Github, and can be retrieved very quickly. For packages that have not been cached, the function must download each version of the package from the CRAN archive, and compare consecutive versions. This process can take considerable time.

The most popular packages on CRAN have been cached. If there is a package you query frequently that has not been cached, please submit an issue to the pkgdiff issue log on Github. In the issue description simply request that the package be added to the cache.

For more information on the package cache, see vignette("pkgdiff-cache").

For more information about how the stability score and assessment are calculated, see vignette("pkgdiff-stability").

Retrieves All Versions of a Package

Description

The pkg_versions function queries the CRAN archive, and returns a data frame of package version information for all releases of the package. This function may be used to understand what versions of a package are available. It is often used in conjunction with pkg_info to get a general overview of a package.

Usage

pkg_versions(pkg)

Arguments

pkg

A package name to return versions for. Pass the package name as a quoted string. This parameter is required.

Value

A data frame with one row per package release, showing the version and date of each release. If the package is not found on CRAN, a message will be generated and the function will return NULL.

Examples

# - Title: The Composer of Plots
# - Maintainer: Thomas Lin Pedersen <thomasp85@gmail.com>
#   - License: MIT + file LICENSE
# - Description: The 'ggplot2' package provides a strong API for sequentially
# building up a plot, but does not concern itself with composition of multiple
# plots. 'patchwork' is a package that expands the API to allow for
# arbitrarily complex composition of plots by, among others, providing
# mathematical operators for combining multiple plots. Other packages that try
# to address this need (but with a different approach) are 'gridExtra' and
# 'cowplot'.

Identify Breakages for a Repository

Description

The repo_breakages function generates a data frame of breakage information for multiple packages. This function can be used to identify breakages for a small set of packages, or even an entire repository.

Usage

repo_breakages(r1 = "current", r2 = "latest")

Arguments

r1

A data frame that identifies the source repository packages and versions. The default value is "current", which means the function will use the current versions of all packages in the current R repository.

r2

A data frame that identifies the target repository packages and versions. The default value is "latest", which means the function will use the latest versions of all packages on CRAN.

Details

The repo_breakages function aims to help with repository upgrades. The purpose is to identify packages that will break if you upgrade your repository.

The function accepts two data frames as input. Each data frame should have two columns: "Package" and "Version". The "r1" data frame is for your current repo. The "r2" data frame is for the upgrade repo.

When executed, repo_breakages will then match up the source and target versions, run a difference operation for each package, and look for breaking changes.

The result will be a table of package names, the source and target version, and whether or not there are any breakages. If there are breakages, the difference object for that package will be added to a "details" list. This difference object can show you exactly which functions or function parameters were removed.

The repo_breakages function is one of primary motivations for the pkgdiff package. This mass-comparison ability did not exist in any other R package prior to pkgdiff.

Value

A list containing a summary table and a list of difference objects. The summary table will contain one row for each package. The columns show the package name, source and target versions, and whether there are any breaking changes between the specified versions. If breaking changes are found, the difference object for that package will be included in the details list.

Examples

# Create package vector
pkgs <- c("curl", "dplyr", "crayon", "stringr")

# Backdated versions
r1 <- data.frame(Package = pkgs,
                 Version = c("5.2.1", "1.1.4", "1.5.2", "1.5.0"))

# More recent versions
r2 <- data.frame(Package = pkgs,
                 Version = c("6.2.1", "1.1.4", "1.5.3", "1.5.1"))

# Find any breaking changes
# res <- repo_breakages(r1, r2) # - Commented out to pass CRAN checks
# Comparing curl v5.2.1/v6.2.1
# Comparing crayon v1.5.2/v1.5.3

Generate Stability Scores for a Repository

Description

The function generates stability scores for a vector of packages. If passing a large number of packages, be prepared for the function to run for a considerable amount of time.

Usage

repo_stability(pkgs, releases = NULL, months = NULL)

Arguments

pkgs

A vector of package names.

releases

An integer number of releases to assess. The function will then limit the scope of the assessment to the specified number of releases.

months

An integer number of months from the current date. The function will then limit the scope of the assessment to the specified number of months.

Details

To assess stability for a package, pkgdiff has to compare all releases of a package, and identify breaking changes between each release. This comparison takes time, especially for packages that have been active for many years.

Therefore, the first step of the function is to compare all releases for each package in the input vector. The function will send messages to the console to let you know which package it is currently comparing. These messages will let you know how far the function is through the processing.

Once all the comparisons are completed, the function will return a data frame summary of stability results. The data frame will have one row for each package in the input vector. The data frame will also show some information about the comparison, and give a stability assessment for each package. The data frame columns are as follows:

Package: The package name.
FV: The first version of the package.
LV: The last version of the package.
FR: The first release date of the package.
LR: The last release date of the package.
TR: The total number of releases.
BR: The number of breaking releases.
Score: The stability score.
Assessment: The stability assessment.

To learn how the package stability score and assessment are calculated, see vignette("pkgdiff-stability"). Additional information is included in the documentation of the pkg_stability function.

If a package is not found in the package cache, the function will download and compare each version of the package on CRAN. This process may increase the processing time. See vignette("pkg-cache") and pkg_cache for additional information.

If a package does not exist on CRAN, a row for that package will still be returned. However, all data values will be NA. This situation may occur if a package exists on Github, but has not yet been submitted to CRAN. The pkgdiff stability functions only work with packages that have been published to CRAN.

Value

A data frame of information regarding the stability of each package in the input vector.

Examples

# Create vector of packages
vct <- c("curl", "dplyr", "rvest", "tidymodels")

# Get stablity scores
res <- repo_stability(vct)
# Getting stability score for package 'curl'...
# Getting stability score for package 'dplyr'...
# Getting stability score for package 'rvest'...
# Getting stability score for package 'tidymodels'...

# View stability results
