Dear Simon, thanks for your help, that clarified a lot. As I could read it is not "recommended" to make the adjustment.
Can RSwitch be called from the command line? If so, one could at least create a command (or alias) "R-2.13" that first calls RSwitch and sets the version accordingly and then starts R. That would be quite convenient.
