It seems that you need to start with ,,an introduction to R'', available at
CRAN (R website) where it is made clear what is list, what is matrix and how
to do anayses with them (there is also mentioned logit).

You need to do something like

glm(y ~ x1 + x2, family=binomial(link=logit))

where x1 and x2 are explanatory variables and y are responses.  Note this is
binomial logit, I have not seen any package able to do multinomial or nested
logit.  There are however many methods for multinominal analysis,
unfortunately I am not familiar with them.

You can download complete R reference manual from CRAN, but I would rather
use a html-form of it (html form should be installed by default).
