how bout:
dat<-data.frame(val=rnorm(100,12,10),x=letters[1:4])
col.val<-ddply(dat,.(x),summarise,mean(val))
col.val$breaks<-cut(col.val$..1,c(0,9,15,Inf))
dat.merge<-merge(dat,col.val)
ggplot(dat.merge,aes(x=x,y=val,colour=breaks))+geom_boxplot()+scale_color_manual(values=c('green','yellow','red'))
