You need to make sure that all the tools are in your path, with the R tools before perl and mingw. Set this by right clicking My Computer, then properties, advanced, environment variables, then edit the path in the system variables window. Once you have done that, you should be able to download the sources (put them in a folder where the path doesn't contain spaces. In addition, it is best if R is in a path that doesn't contain spaces (so C:\Program Files\Rw1080 is not ideal. I usually install in C:\Rw1080, but do what you like.) Next, open a command prompt. Start menu, run, type cmd, enter. Then cd to the folder where the affy.tar.gz resides and type 'tar xvfz affy*gz' without the quotes. After everything is untarred and unzipped, cd to Rw1080\bin and type 'rcmd install '. Windows is case insensitive (mostly), so you don't need to capitalize. You should then see a bunch of stuff happening, hopefully none of which contains an error message. If something doesn't work, re-read Brian Ripley's page on compiling. You can also get good information by downloading the R-1.8.1 tarball and looking for the readme-packages file. HTH, Jim James W.

I went to FAQ R Win then to http://www.stats.ox.ac.uk/pub/Rtools/ and downloaded in The essentials, tools and Perl 5.8.0, then MingW from www.mingw.org and I wonder if I need any other stuff from this page ? I m not sure but I dont think I need the cross-conpilers ? what about the others below ? Then I installed MingW and Perl. Then what am i suposed to do....? If I click on Rcmd I dont get any windows to open or just for a second... thanks for your help Philippe [[alternative HTML version deleted]] ______________________________________________ R-help@stat.math.ethz.ch mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help
