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.
Implementation of the 'viridis', 'magma', 'plasma', 'inferno', and
'cividis' color maps for 'R'. 'viridis', 'magma', 'plasma', and
'inferno' are ported from 'matplotlib', a popular plotting library for
Python. These color maps are designed in such a way that they will
analytically be perfectly perceptually-uniform, both in regular form
and also when converted to black-and-white. They are also designed to
be perceived by readers with the most common form of color blindness
(all color maps in this package) and color vision deficiency
('cividis' only). This is the 'lite' version of the more complete
'viridis' package.
