Get number of occurrence records.

Get number of occurrence records.

occ_count(
  taxonKey = NULL,
  georeferenced = NULL,
  basisOfRecord = NULL,
  datasetKey = NULL,
  date = NULL,
  typeStatus = NULL,
  country = NULL,
  year = NULL,
  from = 2000,
  to = 2012,
  type = "count",

)

Arguments

taxonKey	Species key
georeferenced	Return only occurrence records with lat/long data (TRUE) or those that don't have that data (FALSE, default). Note that you can also get record count with occ_search() by setting limit=0
basisOfRecord	Basis of record
datasetKey	Dataset key
date	Collection date
typeStatus	A type status. See typestatus() dataset for options
country	Country data was collected in, two letter abbreviation. See https://countrycode.org/ for abbreviations.
year	Year data were collected in
from	Year to start at
to	Year to end at
type	One of count (default), schema, basisOfRecord, countries, or year.
publishingCountry	Publishing country, two letter ISO country code
protocol	Protocol. E.g., 'DWC_ARCHIVE'
curlopts	list of named curl options passed on to HttpClient. see curl::curl_options for curl options

Value

A single numeric value, or a list of numerics.

Details

There is a slight difference in the way records are counted here vs. results from occ_search(). For equivalent outcomes, in the occ_search() function use hasCoordinate=TRUE, and hasGeospatialIssue=FALSE to have the same outcome for this function using georeferenced=TRUE.
