Hi,
It should be a matrix of the explanatory variables. Is that really all your
question? Did you look at the help for ?glmnet it shows several examples that
may help you understand how to use it. You can also find useful papers online
from the authors of the book "Elements of Statistical Learning"
Cheers,
Josh
