[R] Multinomial models

[nicole baerg]

Hello,

I am VERY new to R (one week) and I am trying to run a multinomial logit model.
The model I am using is

> model1 <- multinom(Y ~ X1 + X2 + , ..., Xn)

if I put in

> summary(model1)

I get

#Error in function (classes, fdef, mtable)  :
        unable to find an inherited method for function "fitted", for
signature "multinom"

and if I put in

> coef(model1)

I get the coefficients. I would like, however, to get the
coefficients, estimates, Std Erros and t-Ratios and/or z or P>[z]

Also can you change the speficiation of the base category without recoding?

Thanks.

Nicole
