This is a trivial question probably buried in page 21 somewhere of An
Idiot's Guide to R.
In MASS(2) P26 for S-Plus you can write:
but in R 1.5.0 you get the response to such an instruction:
Error: couldn't find function "ordered<-"
What's the fix to this? I have a series of models where the factors as
reported need re-ordering so that the glm reports the coefficients with
respect to the correct level. At the moment, while the solutions are
identical, I actually have to do some arithmetic to show this.
