[R] 'symbols' not plotting correct circle radii

I have been plotting some circles using 'symbols', with radii representing my data, but the radii looked incorrect.
It seems to happen with a single circle too:
Symbols ( 0, 0, circles = 40, xlim = c(-40, 40), ylim= c(-40, 40))
If I put a ruler up to my monitor (technology!) to compare the radius with the axes, the circle isn't radius 40; it is closer to 15...
I suspect there is a simple answer.
