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.
Arguments
- x
auk_ebdorauk_samplingobject; reference to file created byauk_ebd()orauk_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_protocolswithin this package. Multiple protocols are allowed at the same time.
Details
This function can also work with on an auk_sampling object if the
user only wishes to filter the sampling event data.
