[R-sig-teaching] Using R in an introductory stats course for non-stat/math majors using Lock5 text

Tue Dec 3 18:10:31 CET 2019

Also, I am not wedded to a GUI, I'd be happy to just use R but I want to
make sure the code doesn't get interfere with learning the methods and
concepts, which I think at their level is more important.
