R help - Nov 2007 - Question about using “par”

Hi, 
Sorry for bothering your guys again. I am trying to use "par" to put 6
figures into 3 rows and 2 columns. My code is:
 
op <- par(mfrow = c(1, 2))
xyplot(x1+x2+x3 ~ y, data=resulta, type="l", pch=LETTERS[1:3],
lty=c(1:3),
main="For k=3, theata1=1")
xyplot(x1+x2+x3  ~ y, data=resultb, type="l", pch=LETTERS[1:3],
lty=c(1:3),
main="For k=3, theata1=5")
xyplot(x1+x2+x3  ~ y, data=resultc, type="l", pch=LETTERS[1:3],
lty=c(1:3),
main="For k=5, theata1=1")
xyplot(x1+x2+x3  ~ y, data=resultd, type="l", pch=LETTERS[1:3],
lty=c(1:3),
main="For k=5, theata1=5")
xyplot(x1+x2+x3 ~ y, data=resulte, type="l", pch=LETTERS[1:3],
lty=c(1:3),
main="For k=10, theata1=1")
xyplot(x1+x2+x3  ~ y, data=resultf, type="l", pch=LETTERS[1:3],
lty=c(1:3),
main="For k=10, theata1=5")
par(op)
 
 
But I can only get one figure in one page, not 6 figures in one page. Is
there any other parameter I should specify? There is no error indicated.
 
Thank you so much!
Catherine

Rule of thumb: what's documented under the header trellis or lattice does
not
use par.

xyplot is a lattice/trellis function, which does not honor par(...) settings,
but uses package grid for layout and everthing else.

So either use standard plot 
  plot(rnorm(100),rnorm(100))

or do something like:

p = xyplot(whatever....)
print(p,split=c(1,1,2,2), more=TRUE)
p = xyplot(whoever,...
print(p,split=c(1,2,2,2), more=TRUE)

See print.trellis for details.
