I'm have matrix data containing some null values. To fill the null values, I'd like to perform collaborative filtering. As I am studying for R, rather I'd like to use R.

So, Does anyone know how to perform collaborative filtering in R?

Like Ben Bolker said, recommenderlab is the package in R that you can use. A detailed document for the same is available at http://cran.r-project.org/web/packages/recommenderlab/vignettes/recommenderlab.pdf
