[R] Issues getting R to write image files

[Kenny Larsen]

Thanks all, I added the dev.off() and although it didn't solve it it no doubt
tidies things up on closing. I have got it working now, it is something in
the plot(....) line, as removing all teh options solves it. I will work
through adding them in one by one!
