Neal Richardson commented on ARROW-17495:
-----------------------------------------
Per https://github.com/apache/arrow/blob/master/r/R/arrow-package.R#L64-L67,
nse_funcs can't be fully populated until load time.
Feel free to try removing it and seeing what breaks, and be sure to check
benchmarks--I don't know how much overhead there is in re-creating a bunch of
function definitions every time you arrow_eval, maybe it's a lot and maybe it
isn't.
> [R] arrow_eval: do we need both nse_funcs and .cache$functions?
> ---------------------------------------------------------------
>
> Key: ARROW-17495
> URL: https://issues.apache.org/jira/browse/ARROW-17495
> Project: Apache Arrow
> Issue Type: Improvement
> Components: R
> Affects Versions: 9.0.0
> Reporter: Dragoș Moldovan-Grünfeld
> Priority: Minor
>
> Currently we have 2 copies of the same information, once in {{nse_funcs}} and
> once in {{{}.cache$functions{}}}. I wasn't able to figure out the reason for
> this. Maybe I am missing something or maybe this is just legacy code that we
> can update.
