update the transform docs to indicate that it only works with numerical data.
Original question (March 16, 2020):
When transform = "standardize" for GLRM, it appears that only numeric columns are standardized and categorical/binary columns are skipped (which seems like the right approach): and Is that interpretation correct? Either way, is it possible to clarify the treatment of categorical/binary variables in the documentation for transform? https://github.com//h2oai/h2o-3/blob/master/h2o-docs/src/product/data-science/algo-params/transform.rst
