Narrow a query by passing taxonomic identifiers

Source: R/galah_identify.R
galah_identify.Rd

When conducting a search or creating a data query, it is common to identify a known taxon or group of taxa to narrow down the records or results returned. This function allows users to pass scientific names or taxonomic identifiers with pipes to provide data only for the biological group of interest.

Usage

galah_identify(..., search = TRUE)

Arguments

...

one or more scientific names (if search = TRUE) or taxonomic identifiers (if search = FALSE); or an object of class ala_id (from search_taxa), gbifid, or nbnid (from taxize) for international atlases.

search

(logical); should the results in question be passed to search_taxa? Ignored if an object of class ala_id, gbifid, or nbnid is given to ....

Examples

galah_identify() is used to identify taxa you want returned in a search or a data query. It is good to use search_taxa() and search_identifiers() first to check that the taxa you provide to galah_identify() return the correct results.

Specify a taxon. A valid taxon will return an identifier.

galah_identify("reptilia")
#> # A tibble: 1 x 1
#>   identifier                                                                 
#>   <chr>                                                                      
#> 1 urn:lsid:biodiversity.org.au:afd.taxon:682e1228-5b3c-45ff-833b-550efd40c399

Specify more than one taxon at a time.

galah_identify("reptilia", "mammalia", "aves", "pisces")
#> # A tibble: 4 x 1
#>   identifier                                                                 
#>   <chr>                                                                      
#> 1 urn:lsid:biodiversity.org.au:afd.taxon:682e1228-5b3c-45ff-833b-550efd40c399
#> 2 urn:lsid:biodiversity.org.au:afd.taxon:e9e7db31-04df-41fb-bd8d-e0b0f3c332d6
#> 3 urn:lsid:biodiversity.org.au:afd.taxon:5ed80139-31bb-48a8-9f57-42d8015dacbb
#> 4 urn:lsid:biodiversity.org.au:afd.taxon:e22efeb4-2cb5-4250-8d71-61c48bdaa051

Use galah_identify() to narrow your queries

galah_call() %>% 
  galah_identify("Eolophus") %>%
  atlas_counts()
#> # A tibble: 1 x 1
#>    count
#>    <int>
#> 1 856571

If you already know a valid taxon identifier, add it and set search = FALSE.

galah_call() %>% 
  galah_identify("urn:lsid:biodiversity.org.au:afd.taxon:b2de5e40-df8f-4339-827d-25e63454a4a2", 
                 search = FALSE) %>%
  atlas_counts()
#> # A tibble: 1 x 1
#>    count
#>    <int>
#> 1 856571
