[R] One main caption for an mfrow=c(2,1) plot window

Hello,
I'm trying to plot a series of pages in a pdf with one main caption for each page.
Each page should then have two plots in one row, preferably with an own caption.
I can't plot the main caption in a window, and subsequently plot the two graphics (next to each other) below it.

Here is what I've tried. This one almost does the job, but when plotting the two graphics, R generates a new pdf page. The 3 commented lines were another approach I tried but didn't work out. The split.screen() erases what was previously drawn on the device (which is the main caption in my case):

x <- 1:10
y <- 10:1
pdf("sandbox.pdf", width=6.5, height=3)
for(i in 1:3){

   plot.new()
   title("derp")
   op <- par(mfrow=c(1,2))
# split.screen(c(1,2))

   plot(x)
# screen(2)

   plot(y)
# close.screen(c(1,2))

   par(op)
}
dev.off()

Any ideas?

Thanks in advance,
  Alex
