[R] logistic regression: categorical value, and multinomial

[Haibo Huang]

I have two questions:

1. If I want to do a binomial logit, how to handle the
categorical response variable? Data for the response
variables are not numerical, but text.

2. What if I want to do a multinomial logit, still
with categorical response variable? The variable has 5
non-numerical response levels, I have to do it with a
multinomial logit.

Any input is highly appreciated! Thanks!
