Dear Paul,
Could you be more specific about what you mean here?
I don't know the Runger paper so it's hard to tell what it is that
you're looking for.
Blatant plug: I developed a package for hidden Markov models
called depmixS4 that in some sense does what you want: clustering
taking dependencies over time into account by specifying a
transition matrix.
Similarly, there are other packages that fit similar models, searching
for hidden markov model provides a number of them.

Hello All,
Does anyone know of a package that performs constraint-based clusters?
Ideally the package could perform "Time-Ordered Clustering", a
technique
applied in a recent journal article by Runger, Nelson, Harnish
(using MS
Excel). Quote, "in our specific implementation of constrained
clustering, the clustering algorithm remains agglomerative and
hierarchical, but observations or clusters are constrained to only
join
if they are adjacent in time." CRAN searches using variants of
"cluster" and/or "constraint" and/or "time" etc. didn't yield
anything I
could recognize.
Thank you,
Paul
