You didn't get any errors and you _did_ get the means. It's just that
you only gave it a dataset that had only one value per category. The
mean is defined for a single element vector although the sd and var
are not. Look more closely at the example on the help page and you
will see that it has more than one value per category defined by the
two interaction variables

You are still failing to include context. I've seen the Nabble
interface. I KNOW that it is not that difficult to include context.
