Produce a k-fold column vector.
Create a k-fold vector useful for H2O algorithms that take a fold_assignments argument.
h2o.kfold_column(data, nfolds, seed = -1)
A dataframe against which to create the fold column.
The number of desired folds.
A random seed, -1 indicates that H2O will choose one.
Returns an H2OFrame object with fold assignments.
