Log message:
(math/R-SparseM) Updated 1.78 to 1.81

(from inst/ChangeLog)
The version 1.79

1.  Removed a "f_" from the .Fortran call in chol2csr following bug report
by Alex Ballantynea (Melbourne U)

Log message:
(math/R-SparseM) Updated 1.77 to 1.78 (make test fails for now)

The version 1.78

1.  Changed check for symmetry to use all.equal() in response to an error
reported by Brian Ripley.

Log message:
Update all R packages to canonical form.

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.

Log message:
R-SparseM: update to canonical form of an R package.

Log message:
Remove MASTER_SITES= from individual R package Makefiles.

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.
