R help - May 2014 - GLMNet Question for Multinomial Data For Determining The Right Number of Questions

I just started to use the Glmnet function for doing analysis of multinomial
data. See the attached code for the analysis of the Fisher iris data as an
example. My question is. When I want to determine the coefficients for the best
lambda value, it returns more than one set of coefficents.. Which?group of
ceofficents ?is the right set to use for this data set?
