Hi everyone! I am planning to use R and Rcmdr in a basic stat course. I have no access to a computer lab, but I can expect all students to have a laptop. Of couse, I have no control over their OS and in my experience several of them will have Macs. I have Windows. My question is the following: can I expect them to be able to install R, Tcl/Tk and Rcmdr (i.e. does anybody has experinece with it?)
