[R] I can't see plots
Hi, I am using RSPerl package on Ubuntu and Apache2 web server. It is my first experience with R language :-) I have the next code embedded into a Perl CGI: use R; use RReferences; my @x; R::initR(--silent,--no-save); R::library(RSPerl); @x = R::call(rnorm, 10); R::call(plot, [EMAIL PROTECTED]); The CGI works but no plot is shown.

Because you aren't running R interactively, it's trying to open a pdf device. This is failing (file permissions maybe?). You should probably specify exactly what device to open, and if it's something that writes a file, where to write it. Duncan Murdoch Can anybody help me? Thanks!
