CRAN has for some time had a policies page at
and we would like to draw this to the attention of package maintainers. 
  In particular, please

- always send a submission email to CRAN at r-project.org with the package
name and version on the subject line.  Emails sent to individual members 
of the team will result in delays at best.

- run R CMD check --as-cran on the tarball before you submit it.  Do
this with the latest version of R possible: definitely R 2.14.2,
preferably R 2.15.0 RC or a recent R-devel.  (Later versions of R are
able to give better diagnostics, e.g. for compiled code and especially
on Windows. They may also have extra checks for recently uncovered

Also, please note that CRAN has a very heavy workload (186 packages were 
published last week) and to remain viable needs package maintainers to 
make its life as easy as possible.
