Well, yes... but the R raster package allows you to do map algebra and a host of 
other raster functions as well: one may try that before switching to GIS.

It must be noted, however, that the raster package performance is poor when large 
datasets are involved.

For a newbie I would suggest Quantum GIS coupled with its GRASS plug-in instead: 
same power, more friendly UI.
