[R] Fitting a line to a qqplot's points?

[Paul Lynch]

I've made some normal plots of my data using qqplot, and now
I would like to fit a line to the points on the plot and
check the correlation coefficient to have a more objective measure
of how straight the line is.  Is there a simple way of doing that?
(I'm still pretty new to R.)

Thanks,
