Could you provide an example of trying to use pt.cex that "does not do the job"?
Using pt.cex works fine for me when I've used it (R version 3.1.2 both 32 bit and 64 bit). Here's some dummy code that demonstrates that the symbol size changes w/o changing the text size: plot(x=c(0,6),y=c(0,6),type="n") legend(x="bottomright",title="Legend 1, symbol 2 with pt.cex=1.25",legend=c("Item 1","Item 2"),pch=c(1,1),pt.cex=c(1,1.25),col=c('black','blue')) legend(x="topleft",title="Legend 2, symbol 2 with pt.cex=1.75",legend=c("Item 1","Item 2"),pch=c(1,1),pt.cex=c(1,1.75),col=c('black','blue')) see if that works for you? ______________________________________ Allen Bingham Bingham Statistical Consulting aebingh...@gmail.com -----Original Message----- From: Ahmed Attia [mailto:ahmedati...@gmail.com] Sent: Friday, January 30, 2015 1:50 PM To: r-help Subject: [R] pch size in a legend Hi R users, I would like to adjust the pch size in a legend without changing the text size, pt.cex does not do the job.
