Hello: Could anyone point me to a nice example where someone has created methods for "[" on a user defined Class? I looked at the package Matrix but that was a little daunting. I'm looking for someone a little more introductory. I've tried to search the help section and the web but its difficult since "[" isn't searchable. Thanks in advance! Greg [[alternative

Dear R People: I have finally seen the error of my ways and have decided to use ESS for R and S + stuff. However, I have a question right from the beginning. I'm somewhat confused by the installation instructions. Do I install XEMACS or ESS first, please? Windows XP R Version 2.0.1 (S + 6.2) Thanks so much!

I'm trying to get R, Sweave, ESS and XEmacs or emacs all installed and working together on my Windows XP Pro system. I've got R 2.6.0 working just fine, installed from the R Windows installer. I also have CYGWIN_NT-5.1 with XEmacs 21.4 working okay. Can anyone point me to any documentation on how to bring these together so that R code typed in Xemacs can be run in R? I found the ESS

For details: http://vgoulet.act.ulaval.ca/en/emacs/ The plan is to keep my distribution current with R releases. The installation wizard is not all that smart for now, but I'll try to improve it in the future. For example, it creates a HOME environment variable (if it doesn't already exist), but doesn't ask for a value...
