That won't work. In lattice, you use the 'layout' argument to
select the number of columns/rows. This is easiest if you set
up a conditioning variable:
cond <- gl(12, 20, labels = letters[1:12])
x <- rnorm(12*20)
qqmath(~x | cond, layout = c(4, 3))
Note that layout = c(columns, rows), not c(rows, columns).
Since you're new to R, let me also recommend very strongly
that you learn to use the str() function (not needed for
this problem, but undoubtedly indispensible in your further
adventures in R-land).
Nice example, and good recommendation!
(It is difficult to satisfy me:)
How can one know/see, what is traditional graphics, and what is lattice
graphics? Or is it try-and-fail-and-use-the-alternative?
You have to do a fair amount of reading. There's a whole chapter
on base graphics in the Intro to R, which also (briefly) mentions
lattice graphics. And then there's the ggplot2 package ...
Beginners should definitely work through the Intro to R.
It takes time and patience.
