[Gretl-devel] msortby() stumbles over NA / nan

Hi, it seems that msortby() only sorts within "blocks" surrounded by occurrences of NA (showing up as nan in matrices). The rest of the sorting-like functions seem to work ok. Example: <hansl> matrix in = {2; 1; NA; 0; -5} print in matrix check = msortby(in, 1) # not ok print check matrix check = sort(in) # ok print check matrix check = dsort(in) # ok print check matrix check = values(in) # ok print check matrix check = uniq(in) # ok print check </hansl> Thanks, sven
