Hi,

I have a for loop to make 2 types of plots and I'd like to save one
type of plots to a pdf file and the other to another pdf file. How can
I control which plot will be saved to which pdf? Thanks

Why not give them file names that identify the type?

I think he wants

pdf("a.pdf")
pdf("b.pdf")
for(i in 1:n) {
plot something on a.pdf
plot something on b.pdf
}

This is done using dev.prev/dev.next/dev.set: see their help for details.
