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. > > > --- Roland Rau <[EMAIL PROTECTED]> wrote: > >> Hi Tom, >> >> did you check the R for Windows FAQ? >> > http://cran.r-project.org/bin/windows/base/rw-FAQ.html#Can-I-run-R-from-a-CD-or-USB-drive_003f >> >> Hope this helps, >> Roland >> >> >> Tom Backer Johnsen wrote: >>> Recently I came across an interesting web site: >>> http://portableapps.com/.
