[BioC] Script to save plots in Pdf format ( DNAcopy)

[Kasper Daniel Hansen]

pdf() supports multiple pages so if you do

pdf(file = "tmp.pdf")
plot()
plot()
plot()
dev.off()

you'll get one pdf file with three pages.  Not all devices (example:
png()) support multiple pages.  Essentially, move the loop inside the
pdf() call in the two previous emails.
