RArcInfo is a package for the R statistical program to import Arc/Info
V7.x binary coverages. It is based on the library Avcelib written by
Daniel Morissette.

Currently, RArcInfo supports most of the file formats stored by these
type of coverages. The geographical information (arcs, polygons,
topological relationships, etc.) are stored using lists, but all the
tables containing related information are imported into a data frame.

Once the desired data are imported, the user can draw maps, even
filling the polygons according to the value of a given
covariate. Although R is not designed for heavy G.I.S. work, this
package is very helpful to work with binary coverages inside R.
