I get the same style of path as Hadley. This is on Windows 7 Home Premium with SP1. I start R by clicking on the R-2.31.0 icon. I'd assumed that it was a change that came with R-2.13.0! (On 32-bit Windows XP, which I have just checked, I do indeed get the 8.3 paths.)

What actually is supposed to happen is that you get the actual path, with forward slashes in it, unless it contains spaces: then you get the 8.3 version. So John's path has no spaces, and doesn't get converted to 8.3. True 8.3 would also have uppercase PROGRAMS, and only one dot in R-2.13.0 (I forget how that is converted).

I've now clarified the help page. R.home() just looks up the environment variable R_HOME, and then possibly adds some subdir to it. If your front end (e.g. Hadley's rj/Eclipse setup) doesn't initialize R_HOME properly, then you'll get whatever it put there. You can also mess with it using Sys.setenv(R_HOME=junk).
