Better install and run R from a USB flash drive. This will save you the trouble of re-writing the CD as you upgrade and install new packages. Also, you can simply copy the R installation on your work computer (no install rights needed); R will run. HTH, b. From: Hans van Walen <hans_at_vanwalen.com> Date: Fri 27 Aug 2004 - 23:54:53 EST At work I have no permission to install R. So, would anyone know whether it is possible to create a CD with a running R-installation for a windows(XP) pc? And of course, how to? Thank you for your help, Hans van Walen

You should be able to reach this package by launching help.start(), and then browsing its directory in the help browser window. Go to chapter "7. Some Suggestions for Instructors" which tells you how to make a live CD of R in Windows. I haven't tried this, since I don't have Windows, but I sure will when I got to be an "instructor" in a Windows class. cheers, jari oksanen -- Jari Oksanen <jarioksa at sun3.oulu.fi>
I have noticed that R 2.0 did run slower than I thought it should. It's only now that you've raised the issue that I realise how much slower. However since I only use the CD when I am working on other people's machines I can't really say if there are other factors impacting upon the performance. I'll dig up the old disk, make some comparisons and forward the results. The bottom line is that it is not a big issue for me.

BTW, I believe running R 2.0.x from a CD will be a lot slower than 1.9.1 because of lazy loading and frequent file accesses: that's a theoretical issue we intend to address for 2.1.0, but not one anyone has yet commented that it is a problem.
