Hi Nicolas,
You nee to explicitly wrap it in print() when it is inside a loop (if
I'm not mistaken also when inside a function). With lattice loaded,
you can find the specific print methods by methods(print) .
The interpreter handles finding the proper print methods. You just
need to have a clear list in your mind regarding what is base graphics
(e.g.plot) and what is grid graphics (e.g. xyplot and qplot). This is
part of the FAQ which points out that this also applies to any
"source()"-ed code:
http://cran.r-project.org/doc/FAQ/R-FAQ.html#Why-do-lattice_002ftrellis-graphics-not-work_003f
(which points out that this applies to ggplot2 functions as well.)
To further confuse the issue, not all functions named "plot" are
dispatched to base graphics. Some are dispatched to lattice graphics.

From your
example:
pdf("temp1.pdf", width=8, height=8)
for(k in 1) {
print(wireframe(volcano))
}
dev.off()

Hi,
I'm hitting a strange problem where pdf plots that I'm trying to make
are blank, only when produced from within a loop. The pdf contains
0 page.
I've narrowed the problem to this minimal script that invariably
produces an empty pdf with my setup:
pdf("/local/scratch/1.pdf", width=8, height=8)
for (k in 1) {
wireframe(volcano)
}
dev.off()
The odd thing is that
pdf("/local/scratch/1.pdf", width=8, height=8)
wireframe(volcano)
dev.off()
works fine!
Am I doing something wrong here? I've tried on two different systems,
Linux or Mac.
Thanks,
Nico
