@MieszkoKucz @MattDowle Yes

@MattDowle #rdatatable Is there any way to use data.table in r6 class?

@MattDowle @statquant Some of WIP are awaiting confirmation about design decisions. Others are awaiting another PRs that needs to be merged first. Of course there are as well such that doesn't wait for anything and have just been abandoned before completion.

@NA_user_ @statquant And 43 of those 112 PRs are tagged WIP anyway. So there's 69 not 112 (out of 1,415 closed) to be prodding about on twitter. Have a look at merged PRs and compare them to open PRs to see why they aren't merged and perhaps you can help.

hello #rstats #rdatatable devs, I see > 100 prs open on github.com/Rdatatable/dat… some for years (or am I mistaken). I was wondering if you had a particular policy wrt testing prs or if it is particularly hard to ensure it’s good enough

@statquant PRs are tested automatically in CI when submitted. It's enough if a contributor runs R CMD CHECK and it passes fine, plus codecov revealed after submitting PR. This ensures, in technical terms, decent quality of a PRs. It's algos, efficiency etc, is not subject to automated tests

@statquant afaik it's not parallel

Got my daily reminder that that #kdb is in a league of its own. On a 25M rows table to pivot it was 10x faster than #rdatatable dcast function while using a single thread vs 16+ for #rstats. I guess the algo must be different ?
