Re: [R] [FORGED] Extracting specified pages from a lattice ("trellis") object.
Hi Paul, Rolf
I do not know how legal this is but this works if you have spaces around the
ultimate plot due to changes in layout
Changing the layout parameters removes the unwanted space.
ap = dotplot(variety ~ yield | year * site, data=barley,layout = c(2,6))
apm = ap[1:2,3:4]
apm$layout <- c(2,2)
apm

Hi
Does this not do what you want ... ?
allpages <- dotplot(variety ~ yield | year * site, data=barley,
layout=c(2,2))
page2 <- allpages[1:2, 3:4]
print(page2)

Re: [R] [FORGED] Extracting specified pages from a lattice ("trellis") object.
Hi Rolf
do you need to use the layout argument?
The layout is conditioned by the levels of a or unique values if not a factor.
easier with factor
unique(dta$a)
[1] "a" "b" "c" "d" "e" "f" "g" "h" "i" "j" "k" "l"
data.frame( a= unique(dta$a), page = rep(1:3, ea = 4), col = 1:2,row =
rep(1:2, ea = 2))
a page col row
1 a1 1 1
2 b1 2 1
3 c1 1 2
4 d1 2 2
5 e2 1 1
6 f2 2 1
7 g2 1 2
8 h2 2 2
9 i3 1 1
10 j3 2 1
11 k3 1 2
12 l3 2 2
I hope I have got the order right
full dataset
xyplot(y~x|a,data=dta)
bar = xyplot(y~x|a,data = subset(dta, a %in% c("e","f","g","h")) ))
print(bar)
(missed the dotplot requirement) but principle is the same.
you can use packet.number or which.packet if needed to make it simpler
use par.settings to do colours lines etc as well as spacing.

Hmm. Thanks Paul. I may be able to work with that. But what I really
wanted was to take
bar <- dotplot(variety ~ yield | year * site, data=barley)
and then do (something like)
foo <- bar[]
so that foo contains only the second page of bar, and then do print(foo)
to get a plot of (just) the second page. Without re-issuing a
(modified) plot command.
Is that not at all possible?
cheers,
Rolf.

Re: [R] [FORGED] Extracting specified pages from a lattice ("trellis") object.
Hi I think the subsetting works by giving you the panels for the corresponding levels of the conditioning variable(s). Note that, if there is more than one conditioning variable, you will need more than one subsetting index. For example, taking this plot with two conditioning variables and 12 panels in total ... dotplot(variety ~ yield | year * site, data=barley) ... this produces three pages ... dotplot(variety ~ yield | year * site, data=barley, layout=c(2,2)) ... and this produces the second page (both panels for the first conditioning variable and the third and fourth panels for the second conditioning variable) ... dotplot(variety ~ yield | year * site, data=barley, layout=c(2,2))[1:2, 3:4] Hope that helps Paul On 14/04/18 12:25, Rolf Turner wrote: Suppose that (e.g.) xyplot() returns an object "xxx" with (say) 3 pages.
