[R] models for polytomous data

Hi all

I have a dataset whose response is a categorical variable of the
ordinal scale type (6 levels).
I'm interested in building classification models, and I'm wondering if
there is something implemented in R (or its packages) that I'm not aware
of, to treat the ordinal scale measurements straightforwardly. I can think
of the alternative of building a conditional (hierarchical) binomial model
by glm() or other binary classifiers, but besides that I'm kind of at
a loss.
(I'm familiar with classification methods for nominal scales, I haven't 
seen much for the ordinal kind).
thanks in advance
