Dear R users,
I'm making multiple plots within the same pdf page (par(mfcol = c(5,1)), and
want a legend for this at the bottom of all the plots. From previous mails
it has been suggested to use par(xpd=TRUE), increase the margin at the last
plot, and then draw the legend. However, when I do this, the last plot gets
smaller with the same amount I increase the margin with.
The problem seems to be that legend() is drawing inside of the margins of
the last plot. While what I want is to get this legend outside the margins.
Or, extend the margins, without making the plot itself shrink...
Any hints or tips will be greatly appreciated.
Best regards,
Lars

Here is my suggestion, which does not work too well:
pdf("rmsd_open_closed.pdf", height=9)
opar <- par(mfcol = c(4,1), mar=c(4,4,2,1) )
plot()
plot()
plot()
par(mar=c(7,4,2,1))
plot()
par(xpd=TRUE)
legend(0, 8, c("black line", "red line"), col=c(1,2), lty=c(1,1))
par(opar)
dev.off()
