Are there any R rpm's for Mandriva 2008.1? I found a couple of dodgy ones that wouldn't install so far (rpmfind.net).

Hello everyone, I'm currently trying to export a couple of graphs to pdf . Postscript would be fine too, but I'm using odd page dimensions, which seem to be overwritten when using the "ps2pdf" command.

Hello, I'm trying to create birth centile charts from about 90000 birth weights using the package lmsqreg. As this is not a CRAN package I have problems finding any examples, which explain how to estimate the LMS parameters needed for the equivalent degrees of freedom.
