Filter the eBird data by spatial extent

Deprecated, use auk_bbox() instead.

auk_extent(x, extent)

Arguments

x	auk_ebd or auk_sampling object; reference to file created by auk_ebd() or auk_sampling().
extent	numeric; spatial extent expressed as the range of latitudes and longitudes in decimal degrees: c(lng_min, lat_min, lng_max, lat_max). Note that longitudes in the Western Hemisphere and latitudes sound of the equator should be given as negative numbers.

Value

An auk_ebd object.
