The fact that the plot function for this sort of object has a 'scales'
argument suggests to me that it is based on lattice plot functions rather than
on base plot functions. If I'm correct, (and I just checked the code and I
was) then you should read ?xyplot for the scales arguments. There are a couple
of pages to scroll through. Arguments like cex.label that are typical of base
plotting functions would likely not have any effect, and unlike base plot
methods which complain about extraneous arguments, lattice plot functions
generally just ignore such.
For me they do not show up as F1,F2 in your example.
It doesn't make much sense to request the at values of 30 and 40 since you
only gave it a matrix that was 20 x 20.
