Have you tried help.search()? I get this:

 > help.search("huber")
Help files with alias or concept or title matching 'huber' using fuzzy
matching:



huber(MASS)             Huber M-estimator of Location with MAD Scale
hubers(MASS)            Huber Proposal 2 Robust Estimator of Location
                         and/or Scale
rlm(MASS)               Robust Fitting of Linear Models

So you may need a library(MASS) first.

Best,

Jim
