Hi Rich,
I'm not sure if you have a reason outside this toy example to want to
be using list() and group(), but if not I would go with this:
xyplot(y ~ x, main = substitute(expression(alpha == p), list(p = pval)))
Hope this helps,

Step 1: Read the R-FAQ 7.31:
Step 2: Ask yourself whether it is likely that such a small value can
be sensibly distinguished from zero using a program that stores values
in double precision.
Step 3: Consider alternate methods, perhaps logarithms or programs
that are equipped to deal with
