Sorry, missed the plot instruction.
dotplot(sample[ord] ~ obs[ord] | site, data=myex,
[... etc ...]

Hello,
Ok, I hadn't understood. I still don't, not completely. Why do you
want to order 'sample' with reference to 'obs'? It would make sense
only in the case of 'obs' ties. Doesn't it make more sense to order
'sample' within 'site'?
As for keeping 'sample' character it's very simple, I was just trying
to not using facotrs for it. The line that makes of it a Date should
change to
myex$sample <- as.character(as.Date(myex$sample, format="%d/%m/%Y"))
Then, to order, within 'site' use
# first attempt, (Rui's 2nd)
ord <- with(myex, order(site, sample))
And if you now plot it, you'll see the samples ordered and a better y
axis labels placing.

thanks for your reply but I don't think your solution can accomplish
to what
I need...
(I can't see any ordering of the variable "sample" with reference to the
variable "obs")
please keep in mind that for a numer of reasons that I do not mention
here
for the sake of conciseness in my case the variable "sample" must be
espressed as a charachter (because what I proposed here is a
simplification
of the original variable composed by a concatenation of more information
strings than the sampling date itself)
and finally the labels on y axis are still not correctly disposed : same
problem as in my example (also this feature must be properly sorted out)
I think it's necessary to stick on the reordering of varibles but I
can't
figure how jet...
