Running

InstallR["RHomeLocation" -> "C:\\Program Files\\R\\R-3.0.1"]


results in a popup box titled "Version Mismatch" saying

Error: R.DLL version does not match (DLL:3.0.1, expecting: 2.14.0).

Does RLink only work with versions of R at or around v2.14?

This is an issue on Windows only. We are aware of this, and it is planned to get this fixed in the next release of Mathematica. If I get the fix earlier and it is easy enough to create a patch, I will post the workaround here. As far as I know, there is no such issue with R 3.x.x on Linux. Currently, RLink should work on all 2.x.x versions of R (on Windows and Linux, and also on some Mac machines).
