Re: [R] Write text in the Hey Felix,

So basically what you want is a figure containing a block of four plots, with a main title for the figure? If that's the case then something like this should work:

# BEGIN CODE #

par(oma=c(0,0,1,0), mfrow=c(2,2))
for(i in 1:4){
plot(NA,xlim=range(0,10),ylim=range(-5,5))
title(paste("Plot ",i,sep=""))
}

par(mfrow=c(1,1), oma=c(0,0,1,0))
mtext("Main Title", 3, outer = TRUE, cex = par("cex.main"))

#Â END CODE #

You can play about with the margins, but I think that's the general idea. Is this what you're after?
