As there have been no negative reactions to my question last week
CRAN no longer mirrors the daily snapshots of the R sources. Archives
of the official releases are of course still available at every CRAN
node.
All answers I got (thanks to all respondents) had basically the same
content: It is important that the snapshot are available somewhere (to
which I wholeheartedly agree), but it is not important that every
single CRAN node carries them. In fact, it makes only limited sense to
propagate archives that change on a daily basis through a network of
mirror sites. When a snapshot reaches one of the final nodes in the
mirroring process, there are already 2 newer versions available at the
orginal sites ...
Snapshots of the R sources (copy of the current CVS tree) can from now
on be obtained from two sources:
*) Anonymous rsync from rsync.rproject.org. This is probably the best
option if you want to track the R sources on a regular basis,
because it allows to update a copy of the CVS tree downloading only
differences since your last checkout. See http://www.rsync.org for
more information on rsync. If rsync is installed on your system
then
rsync rsync.r-project.org::
gives you a list of available modules, currently including:
r-release R-1.3.1 sources (current released version - approx 25 MB)
r-patched R sources (patched released version - approx 25 MB)
r-devel R sources (devel version, less stable - approx 25 MB)
r-ng R sources (next generation - unstable - approx 25 MB)
Note that rsync connections can be compressed, such that the actual
number of megabytes transferred is approximately the same as
downloading a gzipped tar file.
*) The usual gzipped and bzipped tar files continue to be available by
anonymous FTP from ftp://ftp.stat.math.ethz.ch/Software/R</a>.
Best,
Fritz
