R help - Sep 2009 - Xyplot, multi line title via main, all lines left justified

All,

Below is an xyplot plot with multiple panels and a title produced via main:

library("lattic")
data.ex = data.frame(y = rnorm(10), t = rep(1:5, 2), group = rep(c(0,1),
each = 5))

xyplot(y ~ t | as.factor(group), data = data.ex,
    main = list("Put figure caption here xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
    want this line left justified" ))

I must be mis-interpreting the help description for main under xyplot, and
the descriptions of just, hjust, and vjust in textGrob, since manipulation
of these arguments do not seem to produce the desired result of having the
second line of text left-justified.

Any help much appreciated.

David

This seems to work. You need to choose a suitable value of 'x', as the
default will be to start at the center.

xyplot(y ~ t | as.factor(group), data = data.ex,
       main = textGrob("Put figure caption here
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
want this line left justified", x = 0, hjust = 0))
