R help - Jun 2008 - Cluster analysis using numeric and factor variables

Hi,

Are there any algorithms that handle numeric and factor variables
together in a cluster analysis?

Thank you,
Nagu

If you can define a distance between two vectors (where each one has some
numerical and some categorical coordinates) then you can proceed with any
clustering algorithm.

One possibility to get such a distance is to use RandomForest which can produce
a proximity matrix which can be turned into distance matrix.

Regards,

Moshe.
