Hi,

I have adviced my students to install R and an editor on a USB drive for
working in the computer class. With R everything works fine following these
instructions: http://personal.bgsu.edu/~mrizzo/Rmisc/usbR.htm.

But several editors (e.g., Tinn-R and WinEdt) require administrator rights.
I have found out that Emacs (Vincent Goulet's Emacs for Windows Modified
http://vgoulet.act.ulaval.ca/en/ressources/emacs/windows) can be installed
without administrator rights. There is, however, one problem. I have edited
the site-start.el file and adjusted the path variable:

(setq inferior-R-program-name "G:/r-2.12.0/bin/i386/rterm.exe")

since R is installed on the G drive. Everything works if R is on G, but when
changing the computer, R is usually on another drive and Emacs cannot find
it. Is it possible to handle this case?

XEmacs for Windows requires that the init.el file is in the .xemacs
subdirectory of the "home" directory that is on the hard drive. Is it
possible to have the init.el file on the USB drive?

Thank you!

Hannu
