When I create an kxy object I have been specifying the 'anv' argument within the command to a data frame containing that single variable extracted from the original uploaded data. Is this correct? Later on when I try to compute hell metrics based on speed using the 'lhs.anv.add' and then the 'lhs.filter.anv' command I receive this error:
