I'm attaching a hansl file with a couple of relevant functions which should
cover many real-world cases. These functions assume an Alfred csv file
preprocessed like I described before, which resides in the location specified
in the string argument 'fname'. (This path is taken as-is, so the caller is
responsible for getting it right.)
Very nice. I've been working on a similar thing myself: I've been trying
to re-implement some of the stuff Yi-Nung has been working on
(downloading financial data from Yahoo) in hansl, without having to go
through R to download the data and pre-process it.
Could you share the details of the pre-processing of the Alfred data you
need? It's very possible that this could be done in hansl directly,
thereby removing the python dependency.
