Search datasets in GBIF.
This function does not search occurrence data, only metadata on the datasets that contain occurrence data.
dataset_search( query = NULL, country = NULL, type = NULL, keyword = NULL, publishingOrg = NULL, hostingOrg = NULL, publishingCountry = NULL, decade = NULL, facet = NULL, facetMincount = NULL, facetMultiselect = NULL, limit = 100, start = NULL, pretty = FALSE, return = NULL, curlopts = list() )
query |
Query term(s) for full text search. The value for this
parameter can be a simple word or a phrase. Wildcards can be added to the
simple word parameters only, e.g. |
country |
NOT YET IMPLEMENTED. Filters by country as given in
isocodes$gbif_name, e.g. |
type |
Type of dataset, options include occurrene, metadata, checklist, sampling_event (http://gbif.github.io/gbif-api/apidocs/org/gbif/api/vocabulary/DatasetType.html) |
keyword |
Keyword to search by. Datasets can be tagged by keywords, which you can search on. The search is done on the merged collection of tags, the dataset keywordCollections and temporalCoverages. |
publishingOrg |
Publishing organization. A uuid string. See
|
hostingOrg |
Hosting organization. A uuid string. See
|
publishingCountry |
Publishing country. See options at isocodes$gbif_name |
decade |
Decade, e.g., 1980. Filters datasets by their temporal coverage broken down to decades. Decades are given as a full year, e.g. 1880, 1960, 2000, etc, and will return datasets wholly contained in the decade as well as those that cover the entire decade or more. Facet by decade to get the break down, e.g. /search?facet=DECADE&facet_only=true (see example below) |
facet |
A list of facet names used to retrieve the 100 most frequent values for a field. Allowed facets are: datasetKey, highertaxonKey, rank, status, extinct, habitat, and nameType. Additionally threat and nomenclaturalStatus are legal values but not yet implemented, so data will not yet be returned for them. |
facetMincount |
Used in combination with the facet parameter. Set
|
facetMultiselect |
Used in combination with the facet parameter. Set facetMultiselect=true to still return counts for values that are not currently filtered |
limit |
Number of records to return. Default: 100. Maximum: 1000. |
start |
Record number to start at. Default: 0. Use in combination
with |
pretty |
Print informative metadata using |
return |
Defunct. All components are returned; index to the one(s) you want |
curlopts |
list of named curl options passed on to
|
A data.frame, list, or message printed to console (using
pretty=TRUE).
Some parameters can tak emany inputs, and treated as 'OR' (e.g., a or b or c). The following take many inputs:
