Dear Rs
I have a 3x3 multiple plot. I would like to have a overall legend in
the outer right margin.
>From the help archive, I found that it can be done by setting
par(xpd=NA). However, I couldn't find the correct values
for x and y co-ordinates for the legend. Please find the code snippet below:
par(mfrow=c(3,3), mar=c(4,4,0.9,0.5), oma=c(1,2,2,4),cex.main=1.1)
*postscript(*file=epsfile,onefile=FALSE,horizontal=TRUE*)*
/* some plotting */
par(xpd=NA)
legend(legend=c("2h-opt Exact","1-shift Exact","2p-opt Exact"),
lty=c("solid","dashed","dotdash"),lwd=c(2,2,2),col=c("red","green","black"),
bty="n",cex=0.8)
Thanks in advance
Prasanna
