[Gretl-devel] Re: clean-up of the "Cheat sheet" guide chapter

OK, so here's something much more straightforward IMHO to calculate a per-hour volatility, using the aggregate function: <hansl> nulldata 720 setobs 60 1:1 --time-series # 60 minutes per hour series x = normal() matrix v = aggregate(x, $obsmajor, var) # $obsmajor means hour here print v dataset compact 1    # yields error ! series rv = v[,end] </hansl> HOWEVER, for the "dataset compact 1" line gretl tells me "not supported", and I don't understand why. Shouldn't it be quite easy to compact from any periodicity down to 1? Plus, when I try the compaction in the GUI on this artificially created dataset, the program crashes (disappears). This is 2024d on Windows.
