Filter the eBird data by project code

Some eBird records are collected as part of a particular project (e.g. the Virginia Breeding Bird Survey) and have an associated project code in the eBird dataset (e.g. EBIRD_ATL_VA). 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_project(x, project)

Arguments

x

auk_ebd or auk_sampling object; reference to file created by auk_ebd() or auk_sampling().

project

character; project code to filter by (e.g. "EBIRD_MEX"). Multiple codes are accepted.

Value

An auk_ebd object.

Details

This function can also work with on an auk_sampling object if the user only wishes to filter the sampling event data.

Other filter: auk_bbox(), auk_bcr(), auk_breeding(), auk_complete(), auk_country(), auk_county(), auk_date(), auk_distance(), auk_duration(), auk_exotic(), auk_extent(), auk_filter(), auk_last_edited(), auk_observer(), auk_protocol(), auk_species(), auk_state(), auk_time(), auk_year()
