Error in (function (n, k, preserveDraw = FALSE)  : 
  Invalid Argument: n and k must be integers > 0, n=0 k=1

This should return a 0-row data.frame.

do we have to change this here? or rather in paradox? is this really pressing in PH?

berndbischl commented

or does this create a known bug?

It doesn't create any problems in other packages that I am aware of, but it is an inconsistency in itself.
