Thank you both for your answer. gridDistance seems to do the trick for me. I haven't seen anything in gdistance that could help me but I could be wrong.
As for GRASS, I'll have to get into it one day. This thing looks powerful, but it's pretty much just a name for me so far...

I think there's a package to ease working with R and GRASS if rgdal isn't sufficient for data transfer...
