Following up to some extent on Friday's discussion regarding the 'validation' of R, could I ask the list group's opinion on possible advantages of R over Splus from a pharma/devices perspective? I wish to exclude the obvious price difference, which doesn???t seem to carry as much weight as I would have thought. Besides, I have noticed many former Splus users gravitating towards R, and I suspect that the reasons are not purely economic. I can think of a few advantages of Splus: 1. SeqTrial (of course that means more $) 2. Tech support 3. The warm fuzzies that management seems to get from proprietary software I can also think of a few advantages of R: 1. Based on my personal experiences, simulations requiring a lot of looping seem to run faster. 2. R interfaces with BUGS, for example through BRUGS. 3. The wonderful help list! As always, I am speaking for myself and not necessarily for Edwards Lifesciences. Regards, -Cody Cody Hamilton, PhD Edwards Lifesciences [[alternative HTML version deleted]]
A big one for us is plotmath (for clinical trial reports we put a lot of greek letters and subscripts on plots), and later we will consider migrating a lot of our stuff to the ggplot package which I don't think is available in S-Plus. Lexical scoping is another advantage of R as is the ability to reference files on the internet. Frank
