Hi Jose, I came across this same problem some time ago and I figured out a quite rudimentary solution, I guess. Probably there are more elgant ones (I would love to know them!!!) Basically what I do is: - Split my device up into one more row, very narrow, at the upper part, to host the general title, and then set my first figure to spand across this first row. - Then plot a "ghost" plot in which I have made everything not visible but the Title. Normally you have to adjust the margins for this first "plot" in advance. - Resest the margins - Plot the other plots For example, for a title, plus 4 figures you could use: > layout(matrix(c(1,1,2,3,4,5),3,2, byrow=T),heights=c(1,6,6)) > par(mar=c(0.1,0.1,2,0.1)) > plot(0, main="Your Title", xaxt="n", yaxt="n", xlab="", ylab="",bty="n",col="white") >par(mar=c(c(4, 4, 4, 2))) > plot...what ever... You have to play a bit with the heights parameter of layout to get the division you are happy with (the function layout.show() shows you the position of each plot in your screen). And play also with the margins, maybe. Hope this is of some use to you...

I can't remember syntax exactly, but using the omi argument to par to set the top outer margin and then mtext, to set some margin text, works very well something like par(omi=c(0,0,0.1,0)) # omi is for inches, oma (usage oma=c(0,0,3,0)) is for lines mtext(label="Something") Maybe this link will help you: http://www.stat.auckland.ac.nz/~paul/Talks/Rgraphics.pdf I have a working solution on my home computer I can share if needed Ulrik On 7/4/06, James W.

Hi Ulrik, thanks for your reply. I haven't managed to make it work the way you describe, unfortunately. It seems to affect only the last plot, not the whole figure... I guess I need to investigate this further. If you can send me the example that worked for you I'd appreciate that, as it may help me find out why it doesn't work for me. The link about Rgraphics is quite good, thanks for that! Just for teh record, this is one example of the plots I would like to add text to: par(mfrow=c(2,3)) for (i in 1:3) { plot(log2(RG$Rb[,i]),log2(RG$R[,i]),pch=".") abline(0,1,col="blue")} for (i in 1:3) { plot(log2(RG$Gb[,i]),log2(RG$G[,i]),pch=".") abline(0,1,col="blue")} so that gives me 6 plots in the same figure. I want to be able to add a title to the whole figure... or maybe add other text here and there... using the whole figure, not the individual plots. Thanks for your help!

I can't get that to work either :-( If I use your example, nothing happens. Only when I start using coordinates visible in my *last plot* then the text is visible, and only within that last plot... hmmm, I must be missing something obvious (I'm still newish to this...) this is an example of the figures I am trying to add text to: par(mfrow=c(2,3)) for (i in 1:3) { plot(log2(RG$Rb[,i]),log2(RG$R[,i]),pch=".") abline(0,1,col="blue")} for (i in 1:3) { plot(log2(RG$Gb[,i]),log2(RG$G[,i]),pch=".") abline(0,1,col="blue")} then, anything I try seems to work only for the very last plot of teh series.

As a slightly better (most of the time) and more convenient alternative I have written the function mult.fig() more than 10 years ago {for S-plus at the time}. I still think it's nice and recommendable and even worth installing the 'sfsmisc' package: install.packages("sfsmisc") library(sfsmisc) mult.fig(6, main = "My title") for(i in 1:6) plot(rnorm(50)) ## or look at example(mult.fig) Martin Maechler, ETH Zurich JimMcD> HTH, JimMcD> Jim JimMcD> Ana Conesa wrote: >> Hi Jose, >> >> I came across this same problem some time ago and I figured out a quite >> rudimentary solution, I guess.
