The canonical form [1] of an R package Makefile includes the
following:
- The first stanza includes R_PKGNAME, R_PKGVER, PKGREVISION (as
needed), and CATEGORIES.
- HOMEPAGE is not present but defined in math/R/Makefile.extension to
refer to the CRAN web page describing the package. Other relevant
web pages are often linked from there via the URL field.
This updates all current R packages to this form, which will make
regular updates _much_ easier, especially using pkgtools/R2pkg.

Each R package should include ../../math/R/Makefile.extension, which also
defines MASTER_SITES. Consequently, it is redundant for the individual
packages to do the same. Package-specific definitions also prevent
redefining MASTER_SITES in a single common place.
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.
