So a starting place for porting old SparkR scripts from before the merge could be to identify those methods in the script belonging to the RDD class and be sure they have the namespace identifier tacked on the front. I hope that helps.

If I wanted to modify the old Kmeans and/or LR examples so that the computation happened in Spark what is the best direction to go? Sorry if I am missing something obvious, but based on the NAMESPACE file [3] in the SparkR codebase I am having trouble seeing the obvious direction to go.
