I am a scientist and I used to use SAS for stats, and then started doing loads of bioinformatics in R. Institute decided they werent going to license SAS anymore, and didnt tell us. We get an email the day of, to say no more SAS. Then we have to drop evrything and concert all our SAS models into R.... Cue bitching from instiute leaders as to why we had to halt all publications. Idiots.
