Not "some reason" but the [badly chosen] default of the R Windows Installer.

The R-on-Windows FAQ, as I recall, recommends NOT to install in a path with

Submit a patch, ideally with some demonstration of tests that it is
side-effect free.  

As I recall, I once tried this and got into a frustrating cycle of required
fixes and I promised myself not to touch this again...
