Hi Diego,
It sounds like what you want to do is to cluster 18 "observations" (each of
them are clusters themselves), and then have each of the 18 tips have the
rest of the cluster hierarchy in them.
I don't think this is possible through hclust, BUT, it can (relatively) be
easier to program using a
Hi Diego,
It depends on your what your research questions are. You haven't told us :)
For example, if you wanted to know whether (a) the environmental
distance between lakes is correlated with spatial distance and (b) if
the relationship changes over time you might do a series of Mantel
tests. T
Hi Michael,
I agree with you and I will make this ordination. But I also want to
check a spatial correlation of the variables, so I thought that
comparing the dendrogram of the environmental variables with the
dendrogram of the geographical distances of the lakes it will
indicates if similar lakes
Hello Diego,
This might not be relevant, but on reading your question the first
idea that struck me was that ordination trajectories of your lakes
over time might be more informative than clustering.

Dear R-help,
In my Master thesis I measured 10 variables from 18 lakes. These
measurements were taken 4 times a year in 3 depths, so I have 12
samples from each lake. I know that 12 samples can not be treated as
replications, since they don't correspond to the same environmental
characteristics an
