Something like this:

f=sin(u)
Cairo("example.pdf", type="pdf",width=12,height=12,units="cm",dpi=300)
par(cex.axis=.6,col.axis="grey",ann=FALSE, lwd=.25,bty="n", las=1, tcl=-.2,

abline(v=seq(from=xlim[1], to=xlim[2], length=5), lwd=.25,lty="dotted",
col="grey")

Wow, you must like light colors :) To the point, just set margins, for example par(mar = c(2,2,0.5, 0.5)) (margins are bottom, left, top, right) after the Cairo command. BTW, Cairo doesn't work for me either... but I tried your example by plotting to the screen. Peter Notice how the canvas' margins are relatively far from the plotting area.

I want to save a pdf plot using Cairo, but the canvas of the saved file seems too large when compared to the actual plotted area. Is there a way to control the relation between the canvas size and the size of actual plotting area?
