Dragoș Moldovan-Grünfeld updated ARROW-16253:
---------------------------------------------
Fix Version/s: 9.0.0
> [R] Helper function for casting from float to duration via int64()
> -------------------------------------------------------------------
>
> Key: ARROW-16253
> URL: https://issues.apache.org/jira/browse/ARROW-16253
> Project: Apache Arrow
> Issue Type: Improvement
> Components: R
> Reporter: Dragoș Moldovan-Grünfeld
> Priority: Major
> Fix For: 9.0.0
>
>
> This logic is used in several places in {{R/dplyr-funcs-datetime.R}} and it
> would be great if we could separate it into a standalone helper function. The
> main purpose would be to indicate the float -> int64 -> duration casting
> chain is being used.
>
> Originally raised by [~jonkeane] during a review for one of the lubridate
> bindings.

> {quote}I've seen this line in a few PRs recently — this is to get around the
> fact that we do not have float durations, yeah? I wonder if we should put
> that into a helper function. Not so much to save lines of code, but to
> encapsulate that we have this one workaround that we're using in all of these
> places.
> Then if that workaround is not necessary (or if we find a better one) we can
> change it in one place. We don't need to do that here, but it would be good
> to make a Jira for that if we do want to.
