Anyone tried this, or used other material for Kenneth> teaching data-analysis with R a la V-R? You must have been that you didn't have problems with "MASS". Part of it certainly is because V&R use a very good S programming style. Many things (95%, 98% ??) *do* work out of the box. But the remaining (2-5%) can be a pain, especially if they are hidden, and don't even produce an obvious error message. Kenneth> Q-2: How does R compare with XploRe?

I'm sure XploRe has some (even many?) pluses over R; especially the availability of modern non/semi-parametric curve fitting and other modern statistical methods and the extensive and nicely written documentation.. and ... and... Programming Language: I'd be interested to hear opinions here. I remember having preferred the S language (of which R is a dialect) quite a bit. However, I am severely biased... :-) The big drawback for many of the "R fans" is that it is commercial and only available as binary, and therefore not free in the sense of the Free Software Foundation. [[Also: There is a saying that software is only *really* documented, and usable for scientific purposes if its source code is available (together with more doc..!). However I know that this view is quite extreme, even more than I am .. ;-) ]] Martin Maechler <maechler@stat.math.ethz.ch> <>< Seminar fuer Statistik, ETH-Zentrum SOL G1; Sonneggstr.33 ETH (Federal Inst.
