Is non negative least squares available as a metalearner in subsemble?

Yes, I have a pull request open to add a SL.nnls wrapper to the SuperLearner package, but it has not been merged yet. For now, you can copy-paste the SL.nnls wrapper from here. This will be included in the next version of the SuperLearner package.

Once you have the SL.nnls and predict.SL.nnls functions sourced, you just specify the NNLS metalearner as a string, like usual: metalearner = "SL.nnls".
