Description

This function takes a species list and tries to match a name in theCategorizacion de Especies Amenazadas de Flora Silvestre, checking if the name is listed in tha dataset.

Usage

search_ds043(splist, max_distance = 0.1)

Arguments

splist

A character vector specifying the input taxon, each element including genus and specific epithet and, potentially, infraspecific rank, infraspecific name and author name. Only valid characters are allowed (see base::validEnc).

max_distance

match when comparing the submitted name with the closest name matches in the species listed in the "Categorizacion de Especies Amenazadas de Flora Silvestre". The distance used is a generalized Levenshtein distance that indicates the total number of insertions, deletions, and substitutions allowed to match the two names. It can be expressed as an integer or as the fraction of the binomial name. For example, a name with length 10, and a max_distance = 0.1, allow only one change (insertion, deletion, or substitution). A max_distance = 2, allows two changes.

Value

A character vector that can have three different output values. The first value, "Present," indicates whether the species name is fully matched with the names listed in the 'Categorizacion de Especies Amenazadas de Flora Silvestre'. The second value, "P_updated_name," provides a fuzzy matching of species names. If a species name is not listed in the catalogue, the third value returned will be an empty string.

Examples

 # Search for multiple species vector
splist <- c("Cleistocactus clavispinus",
             "Welfia alfredi",
             "Matucana haynei")

 search_ds043(splist)

 # Search for multiple species data.frame
 # base
 df_splist <- data.frame(splist = splist)
 df_splist$peutimber <- search_ds043(df_splist$splist)
