auk_project: Filter the eBird data by project code

Description

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.

Usage

auk_project(x, project)

Value

An auk_ebd object.

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.

Details

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

Examples

system.file("extdata/ebd-sample.txt", package = "auk") %>%
  auk_ebd() %>%
  auk_project("EBIRD_MEX")
  
# alternatively, without pipes
ebd <- auk_ebd(system.file("extdata/ebd-sample.txt", package = "auk"))
auk_project(ebd, "EBIRD_MEX")
