auk_protocol: Filter the eBird data by protocol

Description

Filter to just data collected following a specific search protocol: stationary, traveling, or casual. 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.

Usage

auk_protocol(x, protocol)

Arguments

x

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

protocol

character. Many protocols exist in the database, however, the most commonly used are:

• Stationary

• Traveling

• Area

• Incidental

A complete list of valid protocols is contained within the vector valid_protocols within this package. Multiple protocols are allowed at the same time.

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.
