Matt> Hey Felix, Matt> So basically what you want is a figure containing a block of four plots, with a main title for the figure?

Is this what you're after? Yes, and since this is so often desired, with our "sfsmisc" package, you can simply say sfsmisc::mult.fig(4, main = "Main Title") for(i in 1:4){ plot(NA,xlim=range(0,10),ylim=range(-5,5)) title(paste("Plot ",i,sep="")) } If you're a good R-citizen, you will want to be able to reset the graphics parameters, which would extend the above to op <- sfsmisc::mult.fig(4, main = "Main Title") $ old.par for(i in 1:4){ plot(NA,xlim=range(0,10),ylim=range(-5,5)) title(paste("Plot ",i,sep="")) } par(op) -- Martin Maechler, ETH Zurich Matt> On Fri Apr 27 15:34 , Felix Wave <[EMAIL PROTECTED]> sent: >> Hello, >> I started a graphic device: >>> par(oma = c(2,0,0,0), mfrow=c(2,2) ) >> >> in the cols and rows are three "image"s. >> Now I want to write a text in the "device region", it's the >> main title of the graphic device.
