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  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.
