Collaborative Filtering with TERR

Hi,

We have a requirement for a recommender system which is supposed to use collaborative filtering method. There is a solution provided with recommenderLab package. But the solution is not yet efficient to be practically used in a Spotfire document. Installing recommerderlab package to TERR also does not provide a significant change in the execution performance for the script.

Does anyone ever implemented a collaborative filtering (it can be user-based or item-based) using TERR functions without additional packages?

Any help/suggestions would be appreciated.

Kind Regards,

Ozgen.
