There's some discussion on the portable apps list about fixing up emacs and getting the drive letter: http://portableapps.com/node/12042 Using: (defvar usb-drive-letter (substring data-directory 0 3)) to get the drive letter from emacs' data-directory variable. You could then paste this onto the start of the path to R. I don't have a windows box with emacs on to muck with the relevant lisp at the moment, but I reckon something like: (defvar usb-drive-letter (substring data-directory 0 3)) (setq inferior-R-program-name (concat usb-drive-letter "r-2.12.0/bin/i386/rterm.exe")) might work. I think the substring gets the whole "X:/" part of the string.
