label the bars by the percentage values in the conditional histogram?

Changbin Du
HI, Dear R-community:

 I have the following codes to plot the conditional histogram, is a way to
label the bars by the percentage values in the conditional histogram?

h<- sample(1:14, 319, rep=T)
c<- sample(1:14, 608, rep=T)
n<- sample(1:14, 1140, rep=T)
vt<-c(h, c, n)
ta<-rep(c("h", "c", "n"), c(319, 608, 1140))

to<-data.frame(vt,ta)

library(lattice)
histogram(~ vt|ta, data=to, layout=c(1,3), labels=TRUE, main="Histograms by
target", col="skyblue")



Thanks so much!
