country: Query the EPPO API Country endpoints.

In eppoFindeR: Interface to the EPPO Database and Public APIs

Query the EPPO API Country endpoints.

Description

This function queries the Country endpoints of the EPPO Global Database via REST API for one or more ISO code(s) and one or more service(s). For each ISO code in isoCodes, the function sequentially queries all specified services and returns the extracted data through a list of dataframes.

Usage

country(
  isoCodes,
  services = c("overview", "categorization", "presence"),
  apiKey = Sys.getenv("EPPO_API_KEY")
)

Arguments

isoCodes	character (vector). One or more ISO codes to query. ISO country codes are standardized identifiers for countries and territories. These codes, typically consisting of two-letter, provide unique and consistent abbreviations of country names. The ISO coding system enables easy management, exchange, and integration of country information across databases and IT systems. ISO country codes and their related data can be accessed via the ISO Online Browsing Platform.
services	character (vector). One or more Country services to query. Common service names include: overview, categorization and presence. A validation step ensures that all provided services match the supported service names. By default: all services.
apiKey	character (string). The API key used for authentication. It can be specified manually or through the .Renviron file. By default: Sys.getenv("EPPO_API_KEY").

Value

A named list of results, in which each level corresponds to the data retrieved for each specified service. Each service element contains a flattened dataframe with the queried content for all the specified ISO codes.

Examples
