[Gretl-users] series indexing

A user wrote me in private, asking me about some oddities on series indexing via strings. I put together a little example: <hansl> nulldata 4 xs = normal(2,1) setobs 1 2000 --time-series # 1: this works xs["2000"] = 3 # 2: this works too a = sprintf("\"2000\"") xs[@a] = 33 # 3: this doesn't a = "2000" xs[a] = 33 </hansl> if assignments 1 and 2 work, one sees no reason why 3 shouldn't work too. Or ami I missing something obvious? ------------------------------------------------------- Riccardo (Jack) Lucchetti Dipartimento di Scienze Economiche e Sociali (DiSES) Università Politecnica delle Marche (formerly known as Università di Ancona) r.lucchetti(a)univpm.it http://www2.econ.univpm.it/servizi/hpp/lucchetti -------------------------------------------------------
