R devel - Nov 2000 - Graphics-Device-Size vs. Window-Size

I want to layout on screen a graphic bigger than the screen (width=16.53543,
height=11.69291) but strwidth() and strheight() give wrong results.
> x11(width=42/2.54, height=29.7/2.54, pointsize=12)
> plot(1,1, type="n", xlim=c(0, 1), ylim=c(-1, 0),
xlab="", ylab="",
axes=FALSE)
> strwidth("Whatever")
[1] 0.08471151
> # Now resize the window and repeat
> strwidth("Whatever")
[1] 0.1856643

strwidth() obviously tells me how much space a text needs ON THE SCREEN, not
on the desired device size. Can someone enlighten what is the best way to
solve this?

Since you are mentioning this again:

Have you looked at  help(strwidth) 
and seen the three different kinds of units that you can ask for ?
