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.

Re: [R] Installing R and an editor on a USB drive
As I recall (my memory may be faulty), Tinn-R installation required admin privileges, but running does not and the installation does not include the specific file path in any files. To make Tinn-R available on a machine where I do not have admin privileges I have a) installed onto a machine where I do have privileges b) copied the entire Tinn-R folder to the target. I guess that could be a USB stick HTH Keith J "PAC2" wrote in message news:1289393991376-3036030.p...@n4.nabble.com... > > Tinn R does not require administrator privileges.

Tinn R does not require administrator privileges. I've installed it on my USB stick and it works fine. -- View this message in context: http://r.789695.n4.nabble.com/Installing-R-and-an-editor-on-a-USB-drive-tp3035839p3036030.html Sent from the R help mailing list archive at Nabble.com. __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
Re: [R] Installing R and an editor on a USB drive
Hey, I don't know whether this helps, but an editor for Windows with code highlighting for any programming language (including R) that can be installed on a pen drive (USB stick) is Notepad++ (http://notepad-plus-plus.org/) and with the NppToR application (http://npptor.sourceforge.net/) that runs in the background, scripts and commands can be sent to R with a configurable keystroke just like with the R editor. I don't really know, though, if NppToR also can be run from the pen drive. I personally like Notepad++ more than TinnR, mostly because it is smaller. It does not, however, provide such a rich development environment like TinnR. Give it a try and see whether it fits your requirements.

Presumably removable or plug-n-play media won't be too consistent and it isn't hard to scan a few drive letters. For example, I just wrote this on cygwin ( hotmail and R spam filter have been redacting my mail, there should be a one line script here LOL ) $ for f in `mount | cut -c 1 | sort | uniq `; do echo `cygpath $f:` ; done /cygdrive/c /cygdrive/d /cygdrive/f The above lists all my drives, f is a flash stick. and you could find one with R and write that to the start file. > since R is installed on the G drive.
