Lack of manpower, I would say. I'm not overly familiar with python, but it certainly is a language worth supporting. > 2) In general, could it be feasible to apply structural changes on > gretl's dataset (i.e. remove/collapse observations) from foreign blocks? > Or will "append" remain the only reasonable channel of communication > from foreign blocks to gretl? No, there's no way to modify the current dataset from a foreign block. However, you could use the foreign block to write the data you need to temporary files (as .mat files for matrices, presumably csv files for a whole dataset) and then, after "end foreign", do a "dataset clear" plus open/join/append/mread()/whatever you need. ------------------------------------------------------- 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 -------------------------------------------------------
