Define a filter for the eBird Basic Dataset (EBD) based on a set of
counties This function only defines the filter and, once all filters have
been defined, auk_filter()
should be used to call AWK and perform the
filtering.
auk_county(x, county, replace = FALSE)
x |
|
---|---|
county | character; counties to filter by. eBird uses county codes
consisting of three parts, the 2-letter ISO country code, a 1-3 character
state code, and a county code, all separated by a dash. For example,
|
replace | logical; multiple calls to |
An auk_ebd
object.
It is not possible to filter by both county as well as country or
state, so calling auk_county()
will reset these filters to all countries
and states, and vice versa.
This function can also work with on an auk_sampling
object if the user only
wishes to filter the sampling event data.
