That's now fixed in CVS. On your second point, there's no automatic way of applying the original series labels to the new series, though you can resort to writing the labels out to file then reading them back, as in <hansl> function list zeroNA (list L) list Lmiss = null loop foreach i L -q series $i = zeromiss(L.$i) Lmiss += $i endloop return Lmiss end function nulldata 20 series x = uniform() series y = uniform() x = x > .2 ? x : 0 y = y > .2 ? y : 0 setinfo x -d "this is series x" setinfo y -d "this is series y" labels --to-file="labels.txt" list L = x y print L -o L = zeroNA(L) labels --from-file="labels.txt" print L -o labels </hansl> Allin Cottrell _______________________________________________ Gretl-users mailing list Gretl-users(a)lists.wfu.edu http://lists.wfu.edu/mailman/listinfo/gretl-users
