[Gretl-devel] Matrix Row-/ column names after selifc()/r()

Hi all, it's cool that row or column names of matrices remain intact when applying the msortby() function. However, when applying row or column selection by means of selifr() or selifc() destroys the attached labels of the respective dimension. See below for examples. This is a bit annoying for practical work. Would it be possible to make sure that the labeling remains intact? Best, Artur <hansl> clear set verbose off matrix M = mnormal(3,2) cnameset(M, defarray("C1", "C2")) rnameset(M, defarray("R1", "R2", "R3")) print M # sorting does not affect row names eval msortby(M,1) eval msortby(M,2) # select rows matrix row_select = {1;1;1} eval selifr(M, row_select) # row names still fine + col names fine matrix row_select = {1;1;0} eval selifr(M, row_select) # row names lost + col names fine matrix row_select = {1;0;1} eval selifr(M, row_select) # row names lost + col names fine # select columns matrix col_select = {1;1}' eval selifc(M, col_select) # col names still fine + row names fine matrix col_select = {1;0}' eval selifc(M, col_select) # col names lost + row names fine matrix col_select = {0;1}' eval selifc(M, col_select) # col names lost + row names fine </hansl>
