cc_gbif: Identify Records Assigned to GBIF Headquarters
Description
Removes or flags records within 0.5 degree radius around the GBIF headquarters in
Copenhagen, DK.
Usage
cc_gbif(
x,
lon = "decimalLongitude",
lat = "decimalLatitude",
species = "species",
buffer = 1000,
geod = TRUE,
verify = FALSE,
value = "clean",
verbose = TRUE
)
Value
Depending on the ‘value’ argument, either a data.frame
containing the records considered correct by the test (“clean”) or a
logical vector (“flagged”), with TRUE = test passed and FALSE = test
failed/potentially problematic . Default = “clean”.
Arguments
x
data.frame. Containing geographical coordinates and species names.
lon
character string. The column with the longitude coordinates.
Default = “decimalLongitude”.
lat
character string. The column with the latitude coordinates.
Default = “decimalLatitude”.
species
character string. The column with the species identity. Only
required if verify = TRUE.
buffer
numerical. The buffer around the GBIF headquarters,
where records should be flagged as problematic. Units depend on geod. Default = 100 m.
geod
logical. If TRUE the radius is calculated
based on a sphere, buffer is in meters. If FALSE
the radius is calculated in degrees. Default = T.
verify
logical. If TRUE records are only flagged if they are the only
record in a given species flagged close to a given reference. If FALSE, the
distance is the only criterion
value
character string. Defining the output value. See value.
verbose
logical. If TRUE reports the name of the test and the number
of records flagged.
Details
Not recommended if working with records from Denmark or the Copenhagen area.
