Trellis graphics and clipping

Even when displayed in the R Graphics Window, there is some clipping (the extreme top, bottom, left and right edges are not there, so that labels, and parts of numerical scale markers all round, have been clipped off). [snip] When I switch to the "postscript" device, with the comamnd 'postscript(filename,...)', the result is even more clipped, [snip] I've tried playing with all the obvious (to me) parameters which I can find, but it has not effect on this.
Follow-up. I've tried the following: hgm<-histogram( ~N | B , xlim=x(0,5), layout=c(5,5) , ... ) print.trellis( hgm , position=c(0.075,0.075,0.925,0.925) ) so as to force down-scaling of the graphic, and now everything is fully displayed in X11: top and bottom scale annotations, bottom label and side label, and all the histograms. No clipping whatever. No problems. Except that there's an error message: Error in unset.gpar(vps[[1]]$gp) : trying to reset with 10 Next, I've done postscript(horizontal=FALSE,onefile=FALSE) and again print.trellis( hgm , position=c(0.075,0.075,0.925,0.925) ) (getting the same error message) and then looked at the resulting PS file. This is again slightly clipped (on the left, as it happens, so that the left label lacks the tops of its letters), but everything else is absolutely fine. OK, print.trellis( hgm , position=c(0.1,0.1,0.925,0.925) ) (same error message). Now, Lo and Behold, when I view the PS file there is no clipping at all. Good! So, apart from this error message (which must mean something, but nevertheless goes with perfect output) all now seems fine. But it still puzzles me that one has to grope for the correct "position" parameter settings for each device. Is there a way to pull all this together?
