spdf_range

A SpatialPolygonsDataFrame representing the distribution of a
species from North America.

datasets

A collection of tools to create species range maps based on
occurrence data, statistics, and spatial objects. Other tools in this
collection can be used to analyze the environmental characteristics of
the species ranges. Plotting options to represent results in various
manners are also available. Results obtained using these tools can be
used to explore the distribution of species and define areas of occupancy
and extent of occurrence of species. Other packages help to explore species
distributions using distinct methods, but options presented in this set of
tools (e.g., using trend surface analysis and concave hull polygons) are
exclusive. Description of methods, approaches, and comments for some of the
tools implemented here can be found in:
