[R] An empty grey diagram

[Joshua Wiley]

It looks like all the packages you should need are loaded.  Does the
call to plot() create a scatter plot correctly?  abline() adds a line
to the current plot so that device still needs to be open when you
call abline() (which it should have been if you ran the code from my
first email).  If a graphic device does not start when you call plot()
then your error is earlier and you may need to explicitly open one (as
David suggested).
