help in conditional histogram
Dear Dr. Sarkar,
When I try to run the codes, I found the following problem:
> 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)
