[R] plotting a 1000 plots?

[Roger Peng]

I believe you can send multiple plots to a pdf file by leaving the pdf()
device open.  By default, each new plot will be put on a different page in
the pdf file.  So,

pdf(file="lotsofplots.pdf")
par(mfcol=c(2,2))
plot(x1,y1)
plot(x2,y2)
plot(x3,y3)
dev.off()

The file 'lotsofplots.pdf' should have three pages. However, I remember
reading on this list somewhere that there's a hard limit of 512 pages to a
file, but I'm not 100% sure.  You may have to use one or two files,
depending on the number of datasets you're plotting. But I suppose that's
better than 1000 files.
