I would second looking at how k approaches dictionaries regarding operations available and their domain. Uniformity between lists, dictionaries and function calls is really elegant there too (although likely out of reach - but maybe still having some parts of syntactic sugar is possible - like having some forms [ ] of notation, yes identity functions have to be renamed may be to x. and y. making it a drastic change, but can we dream?).
But putting syntax aside, at the very minimum, to me, if it is not a tree like structure with keys of arbitrary type, such a thing is not of much added value. After all j is already extremely well equipped to handle rectangular data and people can manage it perfectly well. It is precisely in tree like data structure things get awkward quickly Regards, Danil вт, 1 февр. 2022 г., 10:12 Raul Miller <rauldmil...@gmail.com>: > Another model to think about here is K's implementation, where the symbol > table is a tree, and thus supports contexts which do not have equal length > columns. > > -- > Raul > > On Mon, Jan 31, 2022 at 9:54 PM Ric Sherlock <tikk...@gmail.com> wrote: > > > > otoh, we already have a binding to R where you can deal > > > with dataframes easily – do we want to “compete” here, too? > > > > > > In terms of whether to just adopt/use one of > R's/Pandas'/Polars'/Julia's > > dataframes rather than reinventing the wheel - I think for me that if it > > were possible to use J primitives to interact with the dataframe > directly, > > that would be really compelling.
