Question

I am trying to construct 3 scatter plots together using:

par(mfrow=c(3,1)),pty='s')

but they appear rather small on an A4 size paper. When I used:

par(mfrow=c(3,1)) only, the scatter plots were too stretched out (length wise). Is there anything that can be used to allow me to adjust the size so that they are large enough (3 plots) on an A4 size paper?

This is what I am currently using to plot the fist one:

(apirt$irt12[apirt$surv==1],
apirt$prtemp[apirt$surv==1],
xlab="ave.base of ears (°C)",
ylab="rectal (°C)",
xlim=c(26,42),
ylim=c(30,42),
col='blue')

Thanks,

Baz

You should specify the size of the page, somewhere…

pdf(file="tmp.pdf",width=21/2,height=29.7/2)
op <- par(mfrow=c(3,1), pty="s")  # or c(2,2) 
plot(1:100,cumsum(rnorm(100)))
plot(1:100,cumsum(rnorm(100)))
plot(1:100,cumsum(rnorm(100)))
par(op)
dev.off()
