Hi, I am trying the lattice graphics in R. Let's say, such a little experiment in file myprog.r: f <- function(){ x <- 1:10 y <- x^2 xyplot(y ~ x) } f() Then I run the program:> source("myprog.r")but nothing happens. Manully run f() at the command line:> f()then the figure is shown. This seems to be a bug only associated with lattice graphics, the old style plots do not exibit these behavior. Dongfeng Li
