Den søndag den 13. februar 2022 14.49.06 CET skrev Ric Sherlock <tikk...@gmail.com>: Inspired by recent threads, I've started experimenting with a DataFrame structure in J. I began by building off the 'general/misc/inverted' utilities so that a DataFrame is just a 2-row table, where the first row is a list of labels & the 2nd is an inverted table. It can be installed as 'tables/dataframe' from the following github repository: https://github.com/tikkanz/jdataframe The JArrow bindings that Aaron pointed me at a while back represent a similar data structure as a 2-column table where the labels are in the first column and the "columns" are rows in the 2nd column. (https://github.com/tikkanz/JArrow) I think I need to play with both for a while to see which works better. Obviously there is a lot more to do, but I thought I'd share in case anyone has any thoughts, suggestions or wants to help take the idea further.
