[R] lattice: plotting in a loop
Hi,
I'm having trouble seeing graphics output from lattice xyplot() when called
from inside a for loop:
x - 1:50
for ( i in 1:5 ) {
y - rnorm(x)
xyplot(y~x) # no graphics when inside for-loop
# plot(x,y)# works fine
# Sys.sleep(0.5) # doesn't seem to help
}
The xyplot() is fine outside the loop. Results are the same to X11 device
and to file devices.
I have noticed that there is a delay proportional to the size of the loop,
so presumably xyplot() is computing although the results aren't reaching the
graphics device.
Can anyone suggest a cause or remedy?
This is my first post to the list, although I've picked up a lot of useful
information reading here!

Hi,
it's a FAQ, you need to print() the plot,

Re: [R] lattice: plotting in a loop
Ah, it's a FAQ ... thought I'd looked hard enough. The ignominy, and for a
first post! Well, in any case, thanks a lot Baptiste.
