I want to place four plots on a page, and I would like to have all four
plots share a common title. I have tried the following code, but the
title is centered over the fourth graph and not centered across all four
plots. Does anyone have any suggestions?
R 2.1.1
windows xp
oldpar<-par(mfcol =c(1,4),ask=TRUE)
plot(p,varp)
plot(p,SEp)
plot(p,CVp)
plot(p,ppval)
title(paste("P and 95%CI for a sample size
of",n,"subjects."))
Thanks,
John

John,
try adding the argument outer=T to the title() function
title(paste("P and 95%CI for a sample size
of",n,"subjects."), outer=T)
Cheers
Andrew

Because the 'Subject' of this thread is such common task (for some), I had created the function mult.fig() about ten years ago (in S-plus times). That is now part of the 'sfsmisc' package. After > install.packages("sfsmisc") you can use > sfsmisc::mult.fig(4, main = "main title") and then do your for plots afterwards. mult.fig() has the other advantage of using slightly smaller margins for the single plots, by default, so you get more "real estate" for plotting.

Does anyone have any suggestions?You may want to adjust the "North" parameters for the outer margin area (oma) and the regular margin (mar): # oma and mar: c(South,West,North,East) oldpar <- par(mfcol =c(1,4), oma=c(0,0,2,0), mar=c(5.1,4.1,0,2.1)) plot(1) plot(2) plot(3) plot(4) title("Common title", outer=TRUE) par(oldpar) efg Earl F.
