Hello, I am new to R and need some help with the legend. How can I add a legend for two variables (in two columns) each having multiple values to be explained in the legend. For example: Var 1 Var 2 <symbol> - Higher <symbol> - Higher <symbol> - Avg <symbol> - Avg <symbol> - Lower <symbol> - Lower I know we can use the "ncol" option but not sure how to put in the values of the variable. Can we use the legend function of this? If yes, how? Thank you. -- View this message in context: http://r.789695.n4.nabble.com/Help-needed-with-legend-tp2124457p2124457.html Sent from the R help mailing list archive at Nabble.com.
A small executable example would help here. We don't even know how you are graphing this. There are several packages including lattice and ggplot as well as the base graphs. If you are doing this in base graphics have a look at ?text --- On Mon, 5/3/10, Nish <nisha.muktewar at gmail.com> wrote:> From: Nish <nisha.muktewar at gmail.com> > Subject: [R] Help needed with legend > To: r-help at r-project.org > Received: Monday, May 3, 2010, 3:10 PM > > Hello, > > I am new to R and need some help with the legend.

Something like this?
plot(0,0)
legend.text<-c("VAR
1","Higher","Average","Lower","VAR
2","Higher","Average","Lower")
legend.pch=1:8
legend.col=c(0,1,1,1,0,1,1,1)
legend("bottomright",legend=legend.text,pch=legend.pch,col=legend.col,ncol=2)
-tgs
