Your question assumes there is such a parameter.  I don't believe
this is the case.  Brian Ripley has written a function "eqscplot"
for S-PLUS that does carefully arrange for the x- and y-scales to
be equal.  It is part of the MASS library, and I believe will
become available in CRAN when the copyright issues are finally
sorted (which may be now, but I am not quite sure).
