This is the first announcement of the

		   Comprehensive R Archive Network 

CRAN is a collection of sites which carry identical material, consisting
of the R&R R distribution(s), the contributed extensions, documentation
for R, and binaries.

The CRAN master site can be found at the URL

	ftp://ftp.ci.tuwien.ac.at/pub/R		(Austria)

and is currently being mirrored daily at

	http://lib.stat.cmu.edu/R/CRAN		(U.S.A.)
	ftp://franz.stat.wisc.edu/pub/R		(U.S.A.)
	ftp://ftp.stat.math.ethz.ch/R-CRAN	(Switzerland)

This list should grow within soon.  If you want to become an official
CRAN mirror, please send me a note (Kurt.Hornik at ci.tuwien.ac.at).

Please use the CRAN site closest to you to reduce network load.

The structure of the CRAN tree is as follows.

	src/base		# Source distribution
	src/contrib		# Source for extensions
	doc/			# Documentation
	bin/<platform>		# Binaries

`src/base' contains the official R source distribution as provided by
Ross Ihaka and Robert Gentleman.

`src/contrib' contains code for extension packages.  Currently, there
are acepack, bootstrap, ctest, date, e1071, fracdiff, gee, jpn, oz,
snns, splines, and survival4.  Look at the INDEX file in this directory
for more specific information.  More packages are expected for the near

`bin' is for prebuilt R binaries (the base distribution and extensions),
grouped according to platforms.  Currently, there are only experimental
packages for Debian GNU/Linux.  I hope that `.tar.gz' files with
contents relative to an installation tree (e.g. `bin/', `lib/R/', and
`man/man1/R.1') can be made available soon for all major supported Unix

`doc' is for additional documentation and information on R.

In the short run, the process of `submitting' to CRAN is very simple:
upload to 


and drop me a note (Kurt.Hornik at ci.tuwien.ac.at).  Please indicate the
copyright situation (GPL, ...) in your submission.

In the long run, there will be a form to fill in, and some requirement
of authentication (PGPish, ...), and submission could maybe be done via
WWW.  I am open to suggestions here.
