R help - Feb 2015 - how to draw a legend outside of the plot

Dear R users,

I have three plots, so I tried, for exmple,

par(mfrow=c(2,2))

y1 <- rnorm(100)
y2 <- rnorm(100)
y3<- rnorm(100)

plot(y1);plot(y2);plot(y3)

Here, I'd like to put a legend on the bottom right hand side (empty space).

is it possible?

Thanks for helping,

Kathryn Lord

Hi Kathryn,
Try this at the end of your example:

plot(y3,type="n",axes=FALSE,xlab="",ylab="")
legend(35,1,c("y1","y2","y3"),pch=1:3)
