[R] Single Title for the Multiple plot page

[Stephen Tucker]

Sometimes I just overlay a blank plot and annotate with text.

par(mfrow=c(1,2), oma=c(2,0,2,0))
plot(1:10)
plot(1:10)
oldpar <- par()
par(mfrow=c(1,1),new=TRUE,mar=rep(0,4),oma=rep(0,4))
plot.window(xlim=c(0,1),ylim=c(0,1),mar=rep(0,4))
text(0.5,c(0.98,0.02),c("Centered Overall Title","Centered Subtitle"),
     cex=c(1.4,1))
par(oldpar)
