Hi,
I successfully created 3 screens with the following:
fig.mat<-c(0,.5,.5,.5,1,1,0,0,.5,1,.5,1)
fig.mat<-matrix(fig.mat,nrow=3)
fig.mat
split.screen(fig.mat)
I can plot three different plots on those 3 screens, but when I try the
following:
(Trying to create three graphs with a common x-axis but different y-axis on
screen 1)
screen(1)
par(oma=c(3,3,0,0))
par(fig=c(0,1,0,0.33))
par(mar=c(0,2,0,0.2))
plot(x,y,ylab="juveniles",type="b")
par(fig=c(0,1,0.33,0.66),new=T)
par(mar=c(0,2,0,0.2))
plot(x,y,ylab="males",type="l",xaxt="n")
par(fig=c(0,1,0.66,0.99),new=T)
par(mar=c(0,2,0.2,0.2))
plot(x,y,ylab="females",type="p",xaxt="n")
title(xlab="class",ylab="frequency",outer=T)
Screen 1 seems to expand over the whole plotting device instead of being
restricted to only the region appointed to Screen 1.
Changing "fig=c(0,1,0,0.33)" to " fig=c(0,0.5,0,0.33)" gives me the result I
was looking for. Why do I have to use "fig" in respect to the original plotting
device and not in respect to the new one (screen1) ?
I thought the use of split.screen() gives the advantage of having three regions
that are treated as separate plotting devices, so that my original code should
work. But I guess that I got it wrong ?!?
Thanks for explanations!
