Tommy, The current implementation of the R actor (RExpression) starts an entirely new R session (as though you'd quit and then re started R from the the command line) for every R actor in the workflow. As you know - this can get costly, and I'm afraid you won't be able to keep those libraries loaded across each actor. There has been some development with an alternative R actor implementation (RExpression2) that uses native Java-R bindings and a single R interpreter across actors. I'm still finding kinks in this "JRI" implementation (it can crash _hard_), but feel free to try it out - it may be just what you are looking for in terms of maintaining your environment. -ben
