Just to add to this: QGIS and R under Linux works as well - But as there seem to be slight problems with the grass console under QGRIS, I have the following procedure (QGIS already connected to grass): I start xterm from the grass console in QGIS and in this console R (or emacs...). Works nicely. But it also works directly in the QGIS grass console
