Log message:
(archivers/R-zip) Updated 2.2.2 to 2.3.1

# zip 2.3.1

* The zip shared library now hides its symbols (on platforms that support
  this), to avoid name clashes with other libraries (#98).

# zip 2.3.0

* zip now handles large zip files on Windows (#65, #75, #79, @weshinsley).

* zip now behaves better for absolute paths in mirror mode, and when the
  paths contain a `:` character (#69, #70).

* `zip::unzip()` now uses the process's umask value (see `umask(2)`) on Unix
  if the zip file does not contain Unix permissions (#67).

* Fix segmentation fault when zip file can't be created (#91, @zeehio)

* Fix delayed evaluation error on zipfile when `zip::zip()`
  is used (#92, @zeehio)

* New `deflate()` and `inflate()` functions to compress and uncompress
  GZIP streams in memory.

hashes.

Log message:
(archivers/R-zip) Updated 2.0.4 to 2.1.1
# 2.1.1

This version has no user visible changes.

# 2.1.0

* `unzip_process()` now does not fail randomly on Windows (#60).

* Now all functions handle Unicode paths correctly, on Windows
  as well (#42, #53).

* `unzip_process()` now works when R library is on different drive
  than `exdir` on Windows (#45)

* zip functions now have a `mode` argument to choose how files and
  directories are assembled into the archive. See the docs for
  details.

* zip functions now have a `root` argument, zip changes the working
  directory to this before creating the archive, so all files are
  relative to `root`.

* `zip()` and `zip_append()` are not deprecated any more, as it was
  hard to achieve the same functionality with the other zip functions.

Log message:
(archivers/R-zip) Updated to 2.0.4

# 2.0.4
* `unzip_process()` prints better error messages to the standard error,
  and exits with a non-zero status, on error.

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.
