I bumped into a trivial documentation bug in 1.9.9CVS, italian version. I know it's old, but I'm lazy at updating programs. The explanation of iminr and imaxr is the essentially the same, namely "Returns the column indices of the maxima of the rows of X" and "Returns a vector containing the column indices of the maxima of the rows of X" whereas obviously one deals with the maxima and the other with the minimums. ... it's nice to find something wrong with Gretl occasionally, just to avoid drifting into personality cult :-). Thanks a lot Allin and Jack.
