[Gretl-devel] uniq() on NA-vector

Hi all, I stumbled about the following: <hansl> matrix m = {NA; NA} eval uniq(m) ? eval uniq(m) Data error </hansl> The doc is silent about the case when all entries of the column are NA. I am a bit surprised that this leads to a data error and hence full stop. What about returning an empty matrix in this case? Actually, the same "error" applies to the value() function. Thanks, Artur
