Enrich a Taxonomy File with URLs to Wikipedia-Images

Add URLs to Images from Wikipedia to a file with a taxonomic hierarchy. By default, existing URLs are kept and only missing URLs are filled in.

Usage

enrich_taxonomy_with_images(
  file,
  delim = ",",
  contact = NULL,
  retry = FALSE,
  progress = TRUE,
  quiet = FALSE
)

Arguments

file

path to the csv file

delim

the delimiter used in the file

contact

contact data to pass on in the user agent of the API call to Wikipedia. Starting in 2026, there is a strict rate limit on API calls per minute for calls without contact data. There are two possible ways to pass contact data:

• a string containing an email address.

• a list that specifies an existing Wikipedia account. You need to specify two named elements: "lang" giving the language code of the Wikipedia where the account is registered and "user" giving the user name. Example: list(lang = "de", user = "James Bond").

See the User Agent Policy for more information.

retry

Whether to retry images that have not been found previously.

progress

Whether to show a progress bar.

quiet

Should all output be suppressed?

Value

a taxonomy_graph with added image URLs. The file given by file is overwritten as a side effect.
