Matt> Hey Felix,
Matt> 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:
Matt> # BEGIN CODE #
Matt> par(oma=c(0,0,1,0), mfrow=c(2,2))
Matt> for(i in 1:4){
Matt> plot(NA,xlim=range(0,10),ylim=range(-5,5))
Matt> title(paste("Plot ",i,sep=""))

Matt> par(mfrow=c(1,1), oma=c(0,0,1,0))
Matt> mtext("Main Title", 3, outer = TRUE, cex =
par("cex.main"))
Matt> #?END CODE #
Matt> You can play about with the margins, but I think that's the
general idea. 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)
