Dear all, I am trying to create a lattice plot which consists of 1 xyplot and 2 histograms (each for x and y). My first try was like this: x<-rnorm(1000) y<-rnorm(1000) xy <- xyplot(y~x) hist.x <- histogram(x) hist.y <- histogram(y) print(xy, position=c(0, 0.2, 1, 1), more=TRUE) print(hist.x, position=c(0, 0, 1, 0.33),more=T) print(hist.y, position=c(0.8, 0, 1, 1)) Ok, this is

Hi, there. I have two matrix with identical dimentions. matrix A contains information of 0 and 1, and matrix B contains data.
