Dewey Dunnington commented on ARROW-17461:
------------------------------------------
I'll look into this again because it may have changed...the last time I browsed
the RStudio source for this I remember seeing a lot of hardcoded stuff. I was
looking before because I wanted to customize how some geometry types were
rendered and I remember concluding that {{as.character()}} was my only option.
If you had a shell around an Arrow Array that was a vctrs implementation (I do
something like this in geoarrow but using C Data interface arrays), you can
stuff them into a data.frame losslessly with zero copy (but the RMarkdown
viewer throws errors for this, too, because it tries to serialize the external
pointer and gets back a NULL).

> In RStudio's R Markdown notebook mode, R data.frames get rendered with an
> interactive table browser where you can paginate through it. I haven't looked
> into how this works, but it would be nice if we could do something similar
> with an Arrow Table
