@nealrichardson Proposed changes are complete now, with the following
addition to the `data-types` section of the reference manual. It didn't feel
like a perfect fit in that section, but I couldn't really find a better place,
if you think it would make more sense moved somewhere else I'd be happy for
feedback!
>uint32 (32 bit unsigned integer), uint64 (64 bit unsigned integer), and
int64 (64-bit signed integer) types may contain values that exceed the range of
R's integer type (32-bit signed integer). When these arrow objects are
translated to R objects, uint32 and uint64 are converted to double ("numeric")
and int64 is converted to bit64::integer64. For int64 types, this conversion
can be disabled (so that int64 always yields a bit64::integer64 object) by
setting options(arrow.int64_downcast = FALSE).
