This is a convenience function to get identifiers across all data sources. You can use other get_* functions to get identifiers from specific sources if you like.

  db = c("itis", "ncbi", "eol", "tropicos", "gbif", "nbn", "pow"),
  suppress = FALSE,
  names = NULL,

  db = get_ids_dbs,
  rows = NA,
  suppress = FALSE,
  names = NULL,



(character) Taxonomic name to query.


(character) database to query. One or more of ncbi, itis, eol, tropicos, gbif, nbn, or pow. By default db is set to search all data sources. Note that each taxonomic data source has their own identifiers, so that if you give the wrong db value for the identifier you could get a result, it will likely be wrong (not what you were expecting). If using ncbi and/or tropicos we recommend getting API keys; see taxize-authentication


(logical) suppress cli separators with the database name being queried. default: FALSE


Deprecated, see sci_com


Other arguments passed to get_tsn(), get_uid(), get_eolid(), get_tpsid(), get_gbifid(), get_nbnid().


(numeric) Any number from 1 to infinity. If the default NA, all rows are returned. When used in get_ids this function still only gives back a ids class object with one to many identifiers. See get_ids_ to get back all, or a subset, of the raw data that you are presented during the ask process.


A vector of taxonomic identifiers, each retaining their respective S3 classes so that each element can be passed on to another function (see e.g.'s).


There is a timeout of 1/3 seconds between queries to NCBI.
