Get the TSN code for a search term.

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

Usage

get_tsn(
  sci_com,
  searchtype = "scientific",
  accepted = FALSE,
  ask = TRUE,
  messages = TRUE,
  rows = NA,
  searchterm = NULL,
  ...
)

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_(
  sci_com,
  messages = TRUE,
  searchtype = "scientific",
  accepted = TRUE,
  rows = NA,
  searchterm = NULL,
  ...
)

Arguments

sci_com

character; A vector of common or scientific names. Or, a taxon_state object (see taxon-state)

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.

messages

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.

searchterm

Deprecated, see sci_com

...

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.

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

# When not found
get_tsn("howdy")

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

# 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)
