But the problem here is installing an RPM with a missing dependency .... If you are going to install binary versions of R you must be on the lookout for such things (which seem quite common, unfortunately).

In this case it is much preferable to install R from the sources (or SRPM) to get a current version of R, and then the section `Setting the browser' of the R-admin manual is obviously relevant.
