Re: [R] ggplot2: legend for geom_rug() ..?

[Tim Smith]

Hi,

Here is the corrected code:

library(ggplot2)
ids <- paste('id_',1:3,sep='')
before <- sample(9)
after <- sample(1:10,9)
dat <- as.matrix(cbind(before,after))
rownames(dat) <- rep(ids,3)
position <- c(rep(10,3),rep(13,3),rep(19,3))

mdat <- cbind(melt(dat),position)
colnames(mdat) <- c('ID','Treatment','value','position')

ggplot(mdat, aes(position, value)) + geom_point(aes(colour = Treatment)) +
        geom_rug(subset = .(position < 14),aes(y=NULL),color="orange") + 
        geom_rug(subset = .(position > 14),aes(y=NULL),color="black") 



Alternatively, how do I add a second legend in ggplot2?

thanks!
