R help - Mar 2004 - xyplot inside a for loop problem

Hello everyone

Could someone please explain me why are xyplot() calls inside a for loop
unsuccessful?

Calling plot() is OK but xyplot() just opens the graphics window and that
is all. No error, no warning :-( The same xyplot() outside for loop works
fine.

---------------------------------------------------------
library(lattice)

# OK:
plot(1,2,type='p',main='standalone plot')
# OK:
for (name in 1) plot(1,2,type='p',main='plot in for')

# OK:
xyplot(1~2,type='p',main='standalone xyplot')
# This does not plot anything:
for (name in 1) xyplot(1~2,type='p',main='xyplot in for')
---------------------------------------------------------

Thank you very much for your help

Vaclav

That's because you didn't read R FAQ 7.24.
