[R] splot.screen: multiple plots

[Anne G]

I have multiple conditions that I would like to plot in a
grid. To save space, I don't need the ticks, labels etc on
the plots which are not on the outside.

I tried split.screen, but if it is clearer to use, it seems
pretty rigid since it decides of each screen size apriori
while I need more space for the left column and top or
bottom row screens than for the other plots.

axis(1,tick=FALSE) does not seem to do anything, asp=1 does
not seem to do anything either. par(pty="s") gave it a
somewhate square aspect, But there is a lot of empty space
which must have to do with margins, but setting the margins
did not seem to change anything.

I think I have seen examples like mine in a book, but it
might have been a book on Splus. Do you know where I can
find an example of what I am looking for.

thanks
Anne

here is a simplified example with the same data for all
plots

X<-c(1.00000  3.63168  6.44916 10.17572 20.47440)
Y<-c(0.26 0.56 0.80 0.92 0.88)

numFreq<-7
numdist<-8

coefind <- 1
quartz(display = "", width =15, height = 10, pointsize = 9,
            family = "Helvetica", antialias = TRUE,
autorefresh = TRUE)
par(pty="s")
split.screen(c(numdist,numFreq))

for (inddist in 1:numdist)
	{
	for (indFreq in 1:numFreq)
		{
		indscreen<- indFreq+(inddist-1)*numFreq

			screen(indscreen)
#			mar<-c(1,1,1,0)

			plot(X,Y,
log="x",col="red",xlim=c(1,100),ylim=c(0,1),lab=5, xlab="",
ylab="")
			axis(1,tick=FALSE)
			axis(2,tick=FALSE)

			if( inddist==1)
				{
				title(main=sprintf('Freq =
%d',indFreq));
				}

			if( indFreq==1)
				{
				axis(2, tick=TRUE)
				title(ylab=sprintf('dist =
%d',inddist));
				}
 			if (inddist==8)
				{
				axis(1,tick=TRUE)
				title(xlab="perc face")
				}

			coefind <- coefind+1
		}
	}
close.screen(all = TRUE)    # exit split-screen mode
