Dear R experts,

Having an ordinal response (3 levels) and factors in the predictors set, 
I would like to fit Proportional Odds Group Lasso.

I found several packages that fit the group lasso:
grplasso, grpreg, gglasso and ordPens.

However, they vary penalty and implementation in several ways, but none 
of them is able to fit a proportional odds model.

Did I overlook something? Is there an R package available?

Many thanks for your help!
