taxon: Query the EPPO API Taxon endpoints.

In eppoFindeR: Interface to the EPPO Database and Public APIs

Query the EPPO API Taxon endpoints.

Description

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

Usage

taxon(
  eppoCodes,
  services = c("overview", "infos", "names", "taxonomy", "categorization", "kingdom",
    "hosts", "pests", "vectors", "vectorof", "bca", "bcaof", "photos",
    "reporting_articles", "documents", "standards", "distribution"),
  apiKey = Sys.getenv("EPPO_API_KEY")
)

Arguments

eppoCodes	character (vector). One or more EPPO codes to query. EPPO codes are standardized identifiers for plants and pests (including pathogens). These alphanumeric codes, typically of 5 to 6 letters long, serve as unique, mnemonic abbreviations of scientific names. The EPPO coding system facilitates the management and exchange of organism names across databases and IT systems. EPPO codes and their corresponding data can be accessed via the EPPO Data Services platform.
services	character (vector). One or more Taxon services to query. Common service names include: overview, infos, names, taxonomy, categorization, kingdom, hosts, pests, vectors, vectorof, bca, bcaof, photos, reporting_articles, documents, standards and distribution. 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 EPPO codes.

Examples

## Not run: 
# Get all information about Bemisia tabaci.
taxonData_ <- taxon(eppoCodes = c("BEMITA"))

# Get names data about Bemisia tabaci.
taxonData_ <- taxon(eppoCodes = c("BEMITA"), services = c("names"))

# Get taxonomy and categorization data about Bemisia tabaci and Gossypium
# hirsutum.
taxonData_ <- taxon(
  eppoCodes = c("BEMITA", "GOSHI"),
  services = c("taxonomy", "categorization"))
