[R] logistic regression packages

[Feng Qiu]

Hi All:
           I'm testing a set of data classification algorithms in this paper 
(www.stat.wisc.edu/~loh/treeprogs/quest1.7/mach1317.pdf )
I couldn't find such algorithms in R packages:
           1. LOG: polytomous logistic regression (there was one in MASS 
library: multinom. But after I update MASS library, multinom was lost.)
           2. POL: POLYCLASS algorithm. There is a S-Plus package(polyclass 
library) for this algorithm, so there should be a corresponding package in 
R, but I haven't found it so far.
           Any advice is appreciated.

Best,

Feng
