  overwrite = NULL,
  lines = NULL,
  dbdir = NULL,
  db = td_connect()
)

Arguments

provider	a list (character vector) of provider(s) to be included in the database. By default, will install itis. See details for a list of recognized provider. available provider automatically.
schema	One of "dwc" (for Darwin Core data) or "common" (for the Common names table.)
version	Which version of the taxadb provider database should we use? defaults to latest. See tl_import for details.
overwrite	Should we overwrite existing tables? Default is TRUE. Change to "ask" for interactive interface, or TRUE to force overwrite (i.e. updating a local database upon new release.)
lines	number of lines that can be safely read in to memory at once. Leave at default or increase for faster importing if you have plenty of spare RAM.
