R help - Feb 2007 - lattice graphics and source()

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.
