thanks for the reply. I'm really not bothered with performance, at the end the difference is not that much anyway, what really horrify me is how is it programmed. I remember I wanted to do a statistical test and I could get back the sample size or the p-value calling the same function but with different arguments. I am not a programmer (learned doing my job) but that really disturbed me, even now, writing this. I guess it's just me, as it seems that R is getting more and more attention.
