Doh!
The second loop should be
for (j in i:min(i+3, 16)) {
Thanks for the help!

You do have 40 plots so you should get 10 pages with 4 plots on each page.
However, X11() is only called 4 times that is why you only have four
plot windows popping up. Pages plotted on the same plot window will
override
previous pages, for obvious reasons.
