Post subject:  R-squared value or logit model

Congratulations on a terrific library!

I am using the multinomial logit with some success. However I need McFadden pseudo r-squared values to gauge progress while developing the model. ( http://www.ats.ucla.edu/stat/mult_pkg/f ... uareds.htm )

Does anyone know how to extract: 1- log-likelihood(model)/log-likelihood(null model) ?
