Try setting lty with par.settings:
xyplot(v3~v2,data=xx,
xlab='',
# group=v1,type='l', lty=1:3 ,
groups=v1, type='l',
par.settings = list(superpose.line = list(lty = 1:3)),
auto.key = list(text=levels(as.factor(xx$v1)) , title='',
cex.title=.75,points=F,lines = T,cex=1,
x = .5, y = -0.1,corner = c(0, 0),
between=1,columns=3,between.columns=2),
)
and since 'v1' should be a factor in xx, you don't need the
as.factor() in auto.key.

hi all,
It's not clear to me how (or if) I can pass multiple values for lty to a key in
xyplot?
I've tried: lines=list(lty=1:3), to no avail.
Do I need to use something other than auto.key?
(Deepayan, if you're out there, I have your book and must admit the answer
isn't jumping out at me.)
thanks in advance!

example code:
#____________________________
xx<-data.frame(v1=rep(letters[1:3],rep(3,3)),v2=rep(1:3,3),v3=rep(1:3,rep(3,3)))
xyplot(v3~v2,data=xx,
xlab='',
group=v1,type='l', lty=1:3 ,
auto.key=list(text = levels(as.factor(xx$v1)) , title='',
cex.title=.75,points=F,lines = T,cex=1, x = .5, y = -0.1,corner =
c(0, 0),
between=1,columns=3,between.columns=2),
)
