“I have talked to a few stats people in industry and they have told me that SAS is still king but R is gaining ground, <5%, but if you go to academia that number is growing faster"
This was someone from biotechnology company telling me.
And in my own workplace, our biostatistical department is using Stata a lot.
Personally, I like R. But it wont hurt if you learn all of them, R, SAS and Stata.
