get_countries_by_currency

Description

This function retrieves a list of countries where a specified currency is used. The function is case-insensitive and matches the currency name or part of the name. The output is ordered alphabetically by country name.

Usage

get_countries_by_currency(currency_input, geometry = FALSE)

Arguments

Value

A data frame containing the list of countries that use the specified currency, ordered alphabetically by country name. The columns include country codes (CCA2 and CCA3), common name, capital, continents, currency name, currency symbol, latitude, and longitude. If geometry = TRUE, an additional column for geographic boundaries is included.

Note

The function utilizes the pre-loaded restcountries_data dataset. Ensure that this dataset is loaded before invoking the function. The function uses a case-insensitive regular expression to match the currency name, allowing partial matches. If geometry = TRUE, the function joins with the world_administrative_boundaries dataset, which must also be pre-loaded.

Examples

# Example usage: Find all countries that use the Euro
euro_countries <- get_countries_by_currency("Euro")
print(euro_countries)

# Example usage: Find all countries that use a currency with "dollar" in its name
dollar_countries <- get_countries_by_currency("dollar", geometry = TRUE)
print(dollar_countries)

# Example usage: Find all countries that use the Yen
yen_countries <- get_countries_by_currency("Yen")
print(yen_countries)

get_countries_by_region

Description

This function retrieves a list of countries based on a specified region, subregion, or continent. The function is case-insensitive and orders the countries alphabetically by their common names. If the input does not match any region, subregion, or continent, the function provides a list of all available regions, subregions, and continents.

Usage

get_countries_by_region(country_region_value, geometry = FALSE)

Arguments

Value

A data frame with information on countries within the specified region, subregion, or continent. If geometry = TRUE, the result includes a geometry column with boundary data. If no match is found, a message lists all available regions, subregions, and continents.

Note

This function returns relevant information on countries in a specified region. When geometry = TRUE, it returns an sf object, including spatial data.

Examples

# Example usage: Get a list of countries in Africa
africa_countries <- get_countries_by_region("Africa")
print(africa_countries)

# Example usage: Get countries in a specific continent with geometry included
western_europe_countries <- get_countries_by_region("Western Europe", geometry = TRUE)
print(western_europe_countries)

# Example usage: Get a list of countries in the continent of Asia
asia_countries <- get_countries_by_region("Asia")
print(asia_countries)

get_country_by_calling_code

Description

This function retrieves information about countries based on a specified calling code or part of it. The input can be a root calling code, suffix, or a full calling code, and the function is case-insensitive.

Usage

get_country_by_calling_code(call_code, geometry = FALSE)

Arguments

Value

A data frame containing the information of countries corresponding to the specified calling code, root, or suffixes. If geometry = TRUE, the result will include an additional column for geographic boundaries (as spatial features).

Note

The function utilizes the pre-loaded restcountries_data dataset. Ensure that this dataset is loaded before invoking the function. If geometry = TRUE, the function joins with the world_administrative_boundaries dataset, which must also be pre-loaded.

Examples

# Example usage: Find country information by root calling code
us_info <- get_country_by_calling_code("+1")
print(us_info)

# Example usage: Find country information by calling code suffix and include geometry
uk_info <- get_country_by_calling_code("44", geometry = TRUE)
print(uk_info)

# Example usage: Find country information by full calling code
india_info <- get_country_by_calling_code("+91")
print(india_info)

get_country_info

Description

This function retrieves information about a specific country based on its country code (cca2 or cca3) or common name. The function is case-insentive and provides a comprehensive overview of the selected country If "all" is passed as the input, it returns data for all countries. If the input does not match any country, the function returns a list of all available country names.

Usage

get_country_info(country_value, geometry = FALSE)

Arguments

Value

A data frame with selected country information. If geometry = TRUE, the result includes a geometry column with boundary data, making the returned object ready to be converted to an sf (simple features) data frame for spatial analysis. If the input is "all", it returns data for all countries. If no match is found, a list of all available country names is printed.

Note

The returned data frame includes relevant country details. If geometry = TRUE, an additional column for geographic boundaries is included.

Examples

# Examples usage: Get information for Nigeria
nigeria_info <- get_country_info("Nigeria")
print(nigeria_info)

# Example usage: Get information for a country using it's cca2 code
usa_info <- get_country_info("US")
print(usa_info)
