Ahh - the problem is that the code to create the test/training data for the caravan data redefines train for the simulated data. This is leads to df[train,] to have zero rows, which when passed to the functions does not catch that there n is zero.

Will need to add checks to catch this and throw an error (plus unit test for case when n=0)

Thanks! m
