You're right - easily tested by just re-sizing the graphics box - sort of
counter-intuitive until I remember the clue is in the name - this generates a
CIRCLE, come what may...

We're back to "read the help." ?symbols explictly states that if inches=FALSE
and the axis scales are different, then the x axis coordinates will be used.
And if your axes are different, why would you expect a *circle* to fit both
simultaneously?
Perhaps instead you need plot.ellipse from the plotrix package.
Hi all,
You might want to use draw.circle from the plotrix package, as it tries
to compensate for different axis scales.
