add cex.axis =1.2 to qqunif.plot from lattice library

Dear R user,

The following qqunit.plot function generated correct qq plot,
however, I want to make axis label (1 ,2 ,.....8) have larger size
for publication.  I tried to add cex.axis =1.2 code following the pch
=20, but it does not change size of axis label. I guess lattice
library setting  is different from standard R graphics setting.

Yes indeed things are different.  Read e.g. the help for xyplot() --- a bit
opaque until you get used to it, but the information actually *is* there.

Your example is *far* too complicated for anyone to wade through,
but here is a toy example just using xyplot:

set.seed(42)
x <- 1:10
y <- rnorm(10)
library(lattice)
# Compare:
print(xyplot(y ~ x))
# with:
print(xyplot(y ~ x,scales=list(cex=2)))

To get an overall title you can use "main=", just like in base graphics.
E.g.:

print(xyplot(y ~ x,scales=list(cex=2),
             main="This is a load of dingoes' kidneys."))

If you can't get something like this to work in the context
in which you are interested, then please provide a *minimal* (simple!)
reproducible example illustrating the problem, and someone on this list
will probably be able to help you.

cheers,
