[R] barplot as Trellis graphic

[Agustin Lobo]

Thanks, it was a matter of reshaping the data matrix as I usually have 
it, ie:
datos <- 
data.frame(x=abs(round(rnorm(100,10,5))),y=abs(round(rnorm(100,2,1))),f=factor(round(runif(100,1,3))))

to become:

datos2 <- 
data.frame(V1=c(datos[,1],datos[,2]),"VAR"=c(rep("x",100),rep("y",100)),f=factor(c(datos[,3],datos[,3])))

and then
require(lattice)
barchart(V1~VAR|f,data=datos2)

I get horizontal lines in the bars that I do not understand, though.

Agus
