Is R portable?

I simply installed R onto a USB stick, downloaded my normal packages to it and it works fine under Windows.
Yes, on Windows, but 1) There are other OSes, 2) This didn't just happen: it needed some careful design, including some caching to make it run fast from a USB disk. Unix-alike ports of R are not completely portable, as the path to R_HOME is encapsulated in the R and Rscript front ends. So if on, say, Linux you want to plug in a USB disc then it will only work if you installed R to that USB disk mounted at the same location in the file system, or are prepared to edit the copies of the R script (which had therefore better be mounted read-write). The standard MacOS build has standard paths encapsulated in many places.

Hi Tom, did you check the R for Windows FAQ?
Hope this helps, Roland Tom Backer Johnsen wrote:
Recently I came across an interesting web site: http://portableapps.com/. The idea is simple,
this is software that
is possible to install and run on some type of USB
memory, a stick or
one of these hard disks. I can think of a number
of situations where
this could be handy. In addition memory sticks
are getting cheaper
and more powerful by the day. So: Is it possible to run R off one of these
sticks?
I am also informed that it is possible to run
Latex in this manner.
