At least on my applications, which make use of importr() quite a lot, I notice that there is a significant (but unscientifically observed) delay when using importr(). If the code is already using it somewhere else in the same module, then it would not matter, however (at least IMO). -- Luca Beltrame, Ph.D. - Translational Genomics Unit Oncology Department, Mario Negri Institute
