[R] R-Package for Recursive Partitioning without Classification or Regression

[Bert Gunter]

Tom:

Recursive partitioning requires a response variable because splitting
criteria are based on node purity/homogeneity (by various criteria) of
the responses.

So why did you not just search on "clustering" (e.g. at rseek.org)?
And in particular, have you looked at the CRAN task view on clustering
here:

https://cran.r-project.org/web/views/Cluster.html

If nothing there satisfies your needs, you may need to clarify your query.

Cheers,
Bert
