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",
  publishingCountry = "US",
  protocol = NULL,
  curlopts = list()
)

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.
