I just acquired a copy of "Statistical Models in S", I guess most commonly known as the "white book", and realized to my dismay that most of the code is not directly executable in R, and I was wondering if there was a source discussing the things that are different and what the new ways of calling things are.
For instance, the first obstacle was the solder.balance data set. I found a "solder" data set in rpart, which is very close to it except for the fact that the Panel variable is not a factor, but that's easily fixed. The first problem is the next two calls, on pages 2 and 3. One is "plot(solder.balance)", which is supposed to produce a very different plot than it does in R (I actually don't know the name of the plot, which is part of the problem I guess). Then one is supposed to call "plot.factor(skips ~ Opening + Mask)", which I took to mean: "plot(skips ~ Opening + Mask, data=solder)", and that worked, though I still haven't been able to make a direct call to plot.factor work (I keep getting a "could not find function plot.factor" error). Anyway, just wondered whether there is some page somewhere that discusses these little differences here and there, as I am sure there will be a number of other problems such as these along the way.
