[R] Beginner's question about vgam for zanegbinomial models

I am just starting to use the vgam() function in VGAM to try to fit
zero-altered negative binomial models. So far I have gotten some a test
dataset to run, but can't seem to extract the log-likelihood. That is,
I am using summary(fit)@df.residual to extract the residual df's, but
can't figure out how to do the same for the log-likelihood. Any ideas?
Also, my model includes both smoothed covariates and factors. I can get
the effects for the factors, but am wondering if vgam() provides
statistics and p-values for estimates of factors? If so, how do I get them?
Thanks for your help, I realize these are "beginner" questions and
appreciate your time and patience.
