All good points. That's what I was trying to say too, but you did a better job of it. > In some cases, though, it hurts more than it helps.

For me, the most important benefit of teaching students to use free software is that I am preparing them for the future. Regarding grad students using statistical software: We mostly teach students to use SAS and we don't teach them as much to use R. R is an amazing Free Software program distributed under the GPL and it has really taken over among the professional, academic statisticians. SAS is being used today mostly because it used to be used before -- it is vendor lock-in coupled with the fact that it does an adequate job on certain tasks that we often need to do in our research. A few years ago I wanted to put SAS on a Linux box and SAS Inc. wanted $3,800.00 in the first year. That was the University Discount -- the regular price was $19,000.00 for the first year. R costs $0 every year! Also, R is vastly superior in some ways. Judging from the rate of development, the future for R is extremely bright. It will be unstoppable. Will we drop SAS and start teaching R? I'd do it but most people will prefer to retire than to change their data management and analysis systems that much, then rewrite their course handouts, slides, lecture notes, etc. I understand that, but the students lose in a big way (but if we don't tell them, they won't know). Another big thing is to transition from VMS to UNIX/Linux. People who have been on VMS for 20 years don't want to change. They don't want to learn Linux unless they have to. So students have to learn SAS on VMS instead of R on Linux. They don't have VMS at home, they won't have VMS at their next employer, etc., etc. You get the idea. Mike
