Define a filter for the eBird Basic Dataset (EBD) to only keep complete checklists, i.e. those for which all birds seen or heard were recorded. These checklists are the most valuable for scientific uses since they provide presence and absence data.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_complete(x)

Arguments

x

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

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.
