I don't believe that precompiled binary files for Linux exist, since they would depend very much on which flavour of Linux you are running.

    NKN> It is very time consuming if I download files by files. Is     NKN> there a place a can buy a CD with all the mentioned files? Not that I am aware off. But I would do the following for easy download of all contributed files: Issue from an R session the following commands (mostly untested):

> options(repos=c(CRAN="http://cran.au.r-project.org/"))
> tmp <- available.packages() # Or just use CRAN.packages() ??
## To download all source files
> download.packages(tmp, destdir=".")

## To download all windows binary
> download.packages(tmp, destdir=".", type="win.binary")

If you do it from a Windows machine, you may have to adapt the destdir argument in those commands. Also, if you sit behind a proxy, then you might have to first issue an appropriate 'Sys.putenv("http_proxy"="put your proxy here")' command.

available.packages() does not seem to have a type argument according to its documentation, so I guess that even if it is run under Windows that it returns a list of all source packages available in contrib. If some of those are not available as a precompiled windows binary, the download.packages() command will probably fail with an error, so you have to do the download in bits and pieces, removing offending entries from `tmp' -- but that should be still faster than downloading file by file (presumably by clicking in a web browser?). (The development version of R should now be more robust (Thanks again, Brian) when downloading and just continue downloading the remaining files if it encounters an error. But I don't know where you run (or what to run) R-devel ;-) ).

Hope this helps.

Cheers,
