taxize (version 0.6.0)

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 class 'tsn': as.tsn(x, check = TRUE)

## S3 method for class 'character': as.tsn(x, check = TRUE)

## S3 method for class 'list': as.tsn(x, check = TRUE)

## S3 method for class 'numeric': as.tsn(x, check = TRUE)

## S3 method for class 'data.frame': as.tsn(x, check = TRUE)

## S3 method for class '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 teh 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 inifity. 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 b
...
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 serial numbers (TSN). If a taxon is not found NA. If more than one TSN is found the function asks for user input (if ask = TRUE), otherwise returns NA. Comes with an attribute match to investigate the reason for NA (either 'not found', 'found' or if ask = FALSE 'multi match')

Examples

Run this code
get_tsn(searchterm = "Quercus douglasii")
get_tsn(searchterm = "Chironomus riparius")
get_tsn(c("Chironomus riparius","Quercus douglasii"))
splist <- c("annona cherimola", 'annona muricata', "quercus robur",
		"shorea robusta", "pandanus patina", "oryza sativa", "durio zibethinus")
get_tsn(splist, verbose=FALSE)

# specify rows to limit choices available
get_tsn('Arni')
get_tsn('Arni', rows=1)
get_tsn('Arni', rows=1:2)

# When not found
get_tsn("howdy")
get_tsn(c("Chironomus riparius", "howdy"))

# Using common names
get_tsn(searchterm="black bear", searchtype="c")

# Convert a tsn without class information to a tsn class
as.tsn(get_tsn("Quercus douglasii")) # already a tsn, returns the same
as.tsn(get_tsn(c("Chironomus riparius","Pinus contorta"))) # same
as.tsn(19322) # numeric
as.tsn(c(19322,129313,506198)) # numeric vector, length > 1
as.tsn("19322") # character
as.tsn(c("19322","129313","506198")) # character vector, length > 1
as.tsn(list("19322","129313","506198")) # list, either numeric or character
## dont check, much faster
as.tsn("19322", check=FALSE)
as.tsn(19322, check=FALSE)
as.tsn(c("19322","129313","506198"), check=FALSE)
as.tsn(list("19322","129313","506198"), check=FALSE)

(out <- as.tsn(c(19322,129313,506198)))
data.frame(out)
as.tsn( data.frame(out) )

# Get all data back
get_tsn_("Arni")
get_tsn_("Arni", rows=1)
get_tsn_("Arni", rows=1:2)
get_tsn_(c("asdfadfasd","Pinus contorta"), rows=1:5)

# use curl options
