Clean Home/Away in dataframes into Team/Opponent dataframes

Description

This function converts dataframes with "home_" and "away_" prefixed columns to "team_" and "opponent_", and doubles the rows. This makes sure that there's one row for each team (as opposed to one row for each game).

Usage

clean_homeaway(dataframe, invert = NULL)

Arguments

dataframe

dataframe

invert

a character vector of columns that gets inverted when referring to the away team (e.g. home spread = 1 gets converted to away_spread = -1)

Value

a dataframe with one row per team (twice as long as the input dataframe)

Examples


# a small example dataframe
s <- data.frame(
   game_id = c("2020_20_TB_GB", "2020_20_BUF_KC", "2020_21_KC_TB"),
   game_type = c("CON", "CON", "SB"),
   away_team = c("TB", "BUF", "KC"),
   away_score = c(31L, 24L, 9L),
   home_team = c("GB", "KC", "TB"),
   home_score = c(26L, 38L, 31L),
   location = c("Home", "Home", "Neutral"),
   result = c(-5L, 14L, 22L),
   spread_line = c(3, 3, -3)
 )

clean_homeaway(s, invert = c("result","spread_line"))

Create Player Merge Names

Description

Applies some name-cleaning heuristics to facilitate joins. These heuristics may include:

Usage

clean_player_names(
  player_name,
  lowercase = FALSE,
  convert_lastfirst = TRUE,
  use_name_database = TRUE,
  convert_to_ascii = rlang::is_installed("stringi")
)

Arguments

player_name

a character vector of player names

lowercase

defaults to FALSE - if TRUE, converts to lowercase

convert_lastfirst

defaults to TRUE - converts names from "Last, First" to "First Last"

use_name_database

uses internal name database to do common substitutions (Mitchell Trubisky to Mitch Trubisky etc)

convert_to_ascii

If TRUE, will transliterate to latin-ascii via the stringi package. Defaults to TRUE if the stringi package is installed.

Details

Equivalent to the operation done by ffscrapr::dp_clean_names() and uses the same player name database.

Value

a character vector of cleaned names

Examples


clean_player_names(c("A.J. Green", "Odell Beckham Jr.  ", "Le'Veon Bell Sr."))

clean_player_names(c("Trubisky,      Mitch", "Atwell, Chatarius", "Elliott, Zeke", "Elijah Moore"),
                  convert_lastfirst = TRUE)

Standardize NFL Team Abbreviations

Description

This function standardizes NFL team abbreviations to nflverse defaults. This helps for joins and plotting, especially with the new nflplotR package!

Usage

clean_team_abbrs(abbr, current_location = TRUE, keep_non_matches = TRUE)

Arguments

abbr

a character vector of abbreviations

current_location

If TRUE (the default), the abbreviation of the most recent team location will be used.

keep_non_matches

If TRUE (the default) an element of abbr that can't be matched to any of the internal mapping vectors will be kept as is. Otherwise it will be replaced with NA.

Value

A character vector with the length of abbr and cleaned team abbreviations if they are included in team_abbr_mapping or team_abbr_mapping_norelocate (depending on the value of current_location). Non matches may be replaced with NA (depending on the value of keep_non_matches).

Examples


x <- c("PIE", "LAR", "PIT", "CRD", "OAK", "SL")
# use current location and keep non matches
clean_team_abbrs(x)

# keep old location and replace non matches
clean_team_abbrs(x, current_location = FALSE, keep_non_matches = FALSE)

Clear function cache

Description

This function clears the memoised cache of all functions memoised by nflreadr.

Usage

clear_cache()

.clear_cache()

Value

A success message after clearing the cache.

Examples

clear_cache()

Load .csv / .csv.gz file from a remote connection

Description

This is a thin wrapper on data.table::fread, but memoised & cached for twenty four hours.

Usage

csv_from_url(...)

Arguments

...

Arguments passed on to data.table::fread

input

A single character string. The value is inspected and deferred to either file= (if no \n present), text= (if at least one \n is present) or cmd= (if no \n is present, at least one space is present, and it isn't a file name). Exactly one of input=, file=, text=, or cmd= should be used in the same call.

file

File name in working directory, path to file (passed through path.expand for convenience), or a URL starting http://, file://, etc. Compressed files with extension ‘.gz’ and ‘.bz2’ are supported if the R.utils package is installed.

text

The input data itself as a character vector of one or more lines, for example as returned by readLines().

cmd

A shell command that pre-processes the file; e.g. fread(cmd=paste("grep",word,"filename")). See Details.

sep

The separator between columns. Defaults to the character in the set [,\t |;:] that separates the sample of rows into the most number of lines with the same number of fields. Use NULL or "" to specify no separator; i.e. each line a single character column like base::readLines does.

sep2

The separator within columns. A list column will be returned where each cell is a vector of values. This is much faster using less working memory than strsplit afterwards or similar techniques. For each column sep2 can be different and is the first character in the same set above [,\t |;], other than sep, that exists inside each field outside quoted regions in the sample. NB: sep2 is not yet implemented.

nrows

The maximum number of rows to read. Unlike read.table, you do not need to set this to an estimate of the number of rows in the file for better speed because that is already automatically determined by fread almost instantly using the large sample of lines. nrows=0 returns the column names and typed empty columns determined by the large sample; useful for a dry run of a large file or to quickly check format consistency of a set of files before starting to read any of them.

header

Does the first data line contain column names? Defaults according to whether every non-empty field on the first data line is type character. If so, or TRUE is supplied, any empty column names are given a default name.

na.strings

A character vector of strings which are to be interpreted as NA values. By default, ",," for columns of all types, including type character is read as NA for consistency. ,"", is unambiguous and read as an empty string. To read ,NA, as NA, set na.strings="NA". To read ,, as blank string "", set na.strings=NULL. When they occur in the file, the strings in na.strings should not appear quoted since that is how the string literal ,"NA", is distinguished from ,NA,, for example, when na.strings="NA".

stringsAsFactors

Convert all or some character columns to factors? Acceptable inputs are TRUE, FALSE, or a decimal value between 0.0 and 1.0. For stringsAsFactors = FALSE, all string columns are stored as character vs. all stored as factor when TRUE. When stringsAsFactors = p for 0 <= p <= 1, string columns col are stored as factor if uniqueN(col)/nrow < p.

verbose

Be chatty and report timings?

skip

If 0 (default) start on the first line and from there finds the first row with a consistent number of columns. This automatically avoids irregular header information before the column names row. skip>0 means ignore the first skip rows manually. skip="string" searches for "string" in the file (e.g. a substring of the column names row) and starts on that line (inspired by read.xls in package gdata).

select

A vector of column names or numbers to keep, drop the rest. select may specify types too in the same way as colClasses; i.e., a vector of colname=type pairs, or a list of type=col(s) pairs. In all forms of select, the order that the columns are specified determines the order of the columns in the result.

drop

Vector of column names or numbers to drop, keep the rest.

colClasses

As in utils::read.csv; i.e., an unnamed vector of types corresponding to the columns in the file, or a named vector specifying types for a subset of the columns by name. The default, NULL means types are inferred from the data in the file. Further, data.table supports a named list of vectors of column names or numbers where the list names are the class names; see examples. The list form makes it easier to set a batch of columns to be a particular class. When column numbers are used in the list form, they refer to the column number in the file not the column number after select or drop has been applied. If type coercion results in an error, introduces NAs, or would result in loss of accuracy, the coercion attempt is aborted for that column with warning and the column's type is left unchanged. If you really desire data loss (e.g. reading 3.14 as integer) you have to truncate such columns afterwards yourself explicitly so that this is clear to future readers of your code.

integer64

"integer64" (default) reads columns detected as containing integers larger than 2^31 as type bit64::integer64. Alternatively, "double"|"numeric" reads as utils::read.csv does; i.e., possibly with loss of precision and if so silently. Or, "character".

dec

The decimal separator as in utils::read.csv. If not "." (default) then usually ",". See details.

col.names

A vector of optional names for the variables (columns). The default is to use the header column if present or detected, or if not "V" followed by the column number. This is applied after check.names and before key and index.

check.names

default is FALSE. If TRUE then the names of the variables in the data.table are checked to ensure that they are syntactically valid variable names. If necessary they are adjusted (by make.names) so that they are, and also to ensure that there are no duplicates.

encoding

default is "unknown". Other possible options are "UTF-8" and "Latin-1". Note: it is not used to re-encode the input, rather enables handling of encoded strings in their native encoding.

quote

By default ("\""), if a field starts with a double quote, fread handles embedded quotes robustly as explained under Details. If it fails, then another attempt is made to read the field as is, i.e., as if quotes are disabled. By setting quote="", the field is always read as if quotes are disabled. It is not expected to ever need to pass anything other than \"\" to quote; i.e., to turn it off.

strip.white

default is TRUE. Strips leading and trailing whitespaces of unquoted fields. If FALSE, only header trailing spaces are removed.

fill

logical (default is FALSE). If TRUE then in case the rows have unequal length, blank fields are implicitly filled.

blank.lines.skip

logical, default is FALSE. If TRUE blank lines in the input are ignored.

key

Character vector of one or more column names which is passed to setkey. It may be a single comma separated string such as key="x,y,z", or a vector of names such as key=c("x","y","z"). Only valid when argument data.table=TRUE. Where applicable, this should refer to column names given in col.names.

index

Character vector or list of character vectors of one or more column names which is passed to setindexv. As with key, comma-separated notation like index="x,y,z" is accepted for convenience. Only valid when argument data.table=TRUE. Where applicable, this should refer to column names given in col.names.

showProgress

TRUE displays progress on the console if the ETA is greater than 3 seconds. It is produced in fread's C code where the very nice (but R level) txtProgressBar and tkProgressBar are not easily available.

data.table

TRUE returns a data.table. FALSE returns a data.frame. The default for this argument can be changed with options(datatable.fread.datatable=FALSE).

nThread

The number of threads to use. Experiment to see what works best for your data on your hardware.

logical01

If TRUE a column containing only 0s and 1s will be read as logical, otherwise as integer.

keepLeadingZeros

If TRUE a column containing numeric data with leading zeros will be read as character, otherwise leading zeros will be removed and converted to numeric.

yaml

If TRUE, fread will attempt to parse (using yaml.load) the top of the input as YAML, and further to glean parameters relevant to improving the performance of fread on the data itself. The entire YAML section is returned as parsed into a list in the yaml_metadata attribute. See Details.

autostart

Deprecated and ignored with warning. Please use skip instead.

tmpdir

Directory to use as the tmpdir argument for any tempfile calls, e.g. when the input is a URL or a shell command. The default is tempdir() which can be controlled by setting TMPDIR before starting the R session; see base::tempdir.

tz

Relevant to datetime values which have no Z or UTC-offset at the end, i.e. unmarked datetime, as written by utils::write.csv. The default tz="UTC" reads unmarked datetime as UTC POSIXct efficiently. tz="" reads unmarked datetime as type character (slowly) so that as.POSIXct can interpret (slowly) the character datetimes in local timezone; e.g. by using "POSIXct" in colClasses=. Note that fwrite() by default writes datetime in UTC including the final Z and therefore fwrite's output will be read by fread consistently and quickly without needing to use tz= or colClasses=. If the TZ environment variable is set to "UTC" (or "" on non-Windows where unset vs ‘""' is significant) then the R session’s timezone is already UTC and tz="" will result in unmarked datetimes being read as UTC POSIXct. For more information, please see the news items from v1.13.0 and v1.14.0.

Description

A helper function that returns the upcoming NFL regular season week based on either the nflverse schedules file (as found in load_schedules()) or some date-based heuristics (number of weeks since the first Monday of September)

Usage

get_current_week(use_date = FALSE)

Arguments

use_date

a logical to determine whether to use date-based heuristics to determine current week, default FALSE (i.e. uses schedule file)

Details

Note that the date heuristic will count a new week starting on Thursdays, while the schedule-based method will count a new week after the last game of the previous week, e.g. after MNF is completed. Tan and Ben argued for a while about this.

Value

current nfl regular season week as a numeric

See Also

Other Date utils: most_recent_season()

Examples

{
  
    try({ # schedules file as per default requires online access
    get_current_week()
    })
  
  # using the date method works offline
  get_current_week(use_date = TRUE)
}

Coalescing join

Description

EXPERIMENTAL! This function joins two dataframes together by key, and then coalesces any columns that have shared names (i.e. fills in NAs). A utility function primarily used internally within nflverse to help build player IDs

Usage

join_coalesce(
  x,
  y,
  by = NULL,
  type = c("left", "inner", "full"),
  ...,
  by.x = NULL,
  by.y = NULL,
  sort = TRUE,
  incomparables = c(NA, NaN)
)

Arguments

x, y

dataframes. Will be coerced to data.table

by

keys to join on, as a plain or named character vector

type

one of "left" (all rows of x and matching rows of y), "inner" (matching rows of x and y), "full" (all rows of x and y)

...

other args passed to merge.data.frame()

by.x, by.y

alternate form of keys to join on - if provided, will override by.

sort

whether to sort output by the join keys

incomparables

keys to NOT match on, i.e. NA should not match on NA.

Value

a data.frame joining x and y dataframes together, with every column from both x and y and patching NA values in x with those in y.

Examples


x <- data.frame(id1 = c(NA_character_,letters[1:4]), a = c(1,NA,3,NA,5), b = 1:5 * 10)
y <- data.frame(id2 = c(letters[3:11],NA_character_), a = -(1:10), c = 1:10 * 100)

join_coalesce(x,y, by = c("id1"="id2"))
join_coalesce(x,y, by.x = "id1", by.y = "id2")
