[R] pch size in a legend

[Allen Bingham]

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?

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. R 2.15.2 32 bit.

legend(0,2100, legend=c("2009","2010","2012","2013","2014"),
col = 1,cex=1,lty=NA,pch=c(1,2,6,7,8),lwd=2,bty="n")

Thanks
