The firefox browser is installed in "/usr/lib/firefox-1.0.7" by
default.
How can I change R's browser path?
options(browser="/usr/bin/firefox") is one way. Setting the environment variable R_BROWSER (before starting R) is another. And meddling with the Renviron file, personal or system-wide, is a third method. This information does seem to be a bit tricky to dig out from the R documentation, especially the R_BROWSER bit. I can only find a somewhat oblique reference in the R-admin manual and of course ?Startup points you towards the Renvironment files and $RHOME/etc/Renviron demonstrates what you can set and how.
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.
