vertsearch: Find records using a global full-text search of VertNet...

In rvertnet: Search 'Vertnet', a 'Database' of Vertebrate Specimen Records

Description

Returns any record containing your target text in any field of the record.

Usage

vertsearch(
  taxon = NULL,
  ...,
  limit = 1000,
  compact = TRUE,
  messages = TRUE,
  only_dwc = TRUE,
  callopts = list()
)

Arguments

taxon	(character) Taxonomic identifier or other text to search for
...	(character) Additional search terms. These must be unnamed
limit	(numeric) Limit on the number of records returned. If >1000 results, we use a cursor internally, but you should still get up to the results you asked for. See also bigsearch to get larger result sets in a text file via email.
compact	Return a compact data frame (boolean)
messages	Print progress and information messages. Default: TRUE
only_dwc	(logical) whether or not to return only Darwin Core term fields. Default: TRUE
callopts	curl options in a list passed on to HttpClient, see examples

Details

vertsearch performs a nonspecific search for your input within every record and field of the VertNet archives. For a more specific search, try searchbyterm

Value

A data frame of search results

Examples

## Not run: 
out <- vertsearch(taxon = "aves", "california", limit=3)

# Limit the number of records returned (under 1000)
out <- vertsearch("(kansas state OR KSU)", limit = 200)
# Use bigsearch() to retrieve >1000 records

# Find multiple species using searchbyterm():
# a) returns a specific result
out <- searchbyterm(genus = "mustela", species = "(nivalis OR erminea)")
vertmap(out)

# b) returns a non-specific result
out <- vertsearch(taxon = "(mustela nivalis OR mustela erminea)")
vertmap(out)

# c) returns a non-specific result
splist <- c("mustela nivalis", "mustela erminea")
out <- lapply(splist, function(x) vertsearch(taxon = x, lim = 500))
library("plyr")
out <- ldply(lapply(out, "[[", "data"))
vertmap(out)

# curl options
vertsearch(taxon = "Aves", limit = 10, callopts = list(verbose = TRUE))
# vertsearch(taxon = "Aves", limit = 10, callopts = list(timeout_ms = 10))

## End(Not run)
