taxize (version 0.8.9)

get_tsn: Get the TSN code for a search term.

Description

Retrieve the taxonomic serial numbers (TSN) of a taxon from ITIS.

Usage

get_tsn(searchterm, searchtype = "scientific", accepted = FALSE,
  ask = TRUE, verbose = TRUE, rows = NA, ...)
as.tsn(x, check = TRUE)
# S3 method for tsn
as.tsn(x, check = TRUE)
# S3 method for character
as.tsn(x, check = TRUE)
# S3 method for list
as.tsn(x, check = TRUE)
# S3 method for numeric
as.tsn(x, check = TRUE)
# S3 method for data.frame
as.tsn(x, check = TRUE)
# S3 method for tsn
as.data.frame(x, ...)
get_tsn_(searchterm, verbose = TRUE, searchtype = "scientific",
  accepted = TRUE, rows = NA, ...)

Arguments

searchterm

character; A vector of common or scientific names.

searchtype

character; One of 'scientific' or 'common', or any unique abbreviation

accepted

logical; If TRUE, removes names that are not accepted valid names by ITIS. Set to FALSE (default) to give back both accepted and unaccepted names.

ask

logical; should get_tsn be run in interactive mode? If TRUE and more than one TSN is found for the species, the user is asked for input. If FALSE NA is returned for multiple matches.

verbose

logical; should progress be printed?

rows

numeric; Any number from 1 to infinity. If the default NA, all rows are considered. Note that this function still only gives back a tsn class object with one to many identifiers. See get_tsn_ to get back all, or a subset, of the raw data that you are presented during the ask process.

...

Ignored

x

Input to as.tsn

check

logical; Check if ID matches any existing on the DB, only used in as.tsn

Value

A vector of taxonomic identifiers as an S3 class. If a taxon is not found an NA is given. If more than one identifier is found the function asks for user input if ask = TRUE, otherwise returns NA. If ask=FALSE and rows does not equal NA, then a data.frame is given back, but not of the uid class, which you can't pass on to other functions as you normally can.

Comes with the following attributes:

• match (character) - the reason for NA, either 'not found', 'found' or if ask = FALSE then 'NA due to ask=FALSE')

• multiple_matches (logical) - Whether multiple matches were returned by the data source. This can be TRUE, even if you get 1 name back because we try to pattern match the name to see if there's any direct matches. So sometimes this attribute is TRUE, as well as pattern_match, which then returns 1 resulting name without user prompt.

• pattern_match (logical) - Whether a pattern match was made. If TRUE then multiple_matches must be TRUE, and we found a perfect match to your name, ignoring case. If FALSE

• uri (character) - The URI where more information can be read on the taxon - includes the taxonomic identifier in the URL somewhere
