lattice dotplot reorder contiguous levels
I don't entirely understand what you want as an alternative. What is wrong with relation ="same", the default? In any case, it sounds like you'll need to write your own panel function. If you look at panel.dotplot(), you'll see it's fairly straightforward, so modification should not be difficult. BTW, thanks for the reproducible example. I wouldn't have bothered at all without it, although maybe the result is the same so far as your concerned. Cheers, Bert

3L, 2L, 4L, 4L, 4L, 4L, 4L, 1L, 4L, 6L, 4L, 8L, 4L, 8L, 4L, 3L,

"4", "12", "24", "96", "135", "167", "168", "169"), class = "factor")),
.Names = c("site",
"conc", "samp.time"), row.names = c(NA, 52L), class = "data.frame")
dotplot(samp.time~conc|site, data=test,
scales=list(x=list(log=10), y = list(relation = "same")),
layout=c(1,5), strip=FALSE, strip.left=TRUE
)
my objective is to use ?site? as conditioning variable but with ?samp.time?
correctly grouped by ?site?; the problem here is to ensure that levels of
?samp.time? within each ?site? are contiguous as otherwise they would be not
contiguous in the dot plot itself (i.e, avoid that sort of holes in between
y axis categories -see dotplot -)
I?ve been trying with this but without much success
test$samp.time.new<-
with(test,reorder(samp.time,as.numeric(site)))
dotplot(samp.time.new~conc|site, data=test,
scales=list(x=list(log=10), y = list(relation = "free")),
layout=c(1,5), strip=FALSE, strip.left=TRUE
)
I think (I hope) a possible different solution is to create for "ylim" a
proper character vector of different length to pass to each panel of the
dotplot (I?m not posting this attempt because too much confused up to now)
can anyone point me in the right direction?
any help much appreciated
thank you
