filter_rank: Get all members (descendants) of a given rank level

In taxadb: A High-Performance Local Taxonomic Database Interface

Get all members (descendants) of a given rank level

Description

Get all members (descendants) of a given rank level

Usage

filter_rank(
  name,
  rank,
  provider = getOption("taxadb_default_provider", "itis"),
  version = latest_version(),
  collect = TRUE,
  ignore_case = TRUE,
  db = td_connect()
)

Arguments

name	taxonomic scientific name (e.g. "Aves")
rank	taxonomic rank name. (e.g. "class")
provider	from which provider should the hierarchy be returned? Default is 'itis', which can also be configured using ⁠options(default_taxadb_provider=...")⁠. See ⁠[td_create]⁠ for a list of recognized providers.
version	Which version of the taxadb provider database should we use? defaults to latest. See tl_import for details.
collect	logical, default TRUE. Should we return an in-memory data.frame (default, usually the most convenient), or a reference to lazy-eval table on disk (useful for very large tables on which we may first perform subsequent filtering operations.)
ignore_case	should we ignore case (capitalization) in matching names? Can be significantly slower to run.
db	a connection to the taxadb database. See details.

Value

a data.frame in the Darwin Core tabular format containing the matching taxonomic entities.
