Dragoș Moldovan-Grünfeld created ARROW-15858:
------------------------------------------------
Summary: [R][C++] Support duration creation from integer
Key: ARROW-15858
URL: https://issues.apache.org/jira/browse/ARROW-15858
Project: Apache Arrow
Issue Type: Bug
Components: C++, R
Reporter: Dragoș Moldovan-Grünfeld
I would expect both {{a}} and {{b}} to create a {{duration}} object of 32
seconds, but the second one returns an {{int32}}
{code:r}
library(arrow, warn.conflicts = FALSE)
a <- as.difftime(32, units = "secs")
b <- as.difftime(32L, units = "secs")
Array$create(a)
#> Array
#> <duration[s]>
#> [
#> 32
#> ]
Array$create(b)
#> Array
#> <int32>
#> [
#> 32
#> ]
{code}
If I try to be explicit, I get somewhat of a clue why that might be happening:
{code:r}
Array$create(a, type = duration())
#> Array
#> <duration[s]>
#> [
#> 32
#> ]
Array$create(b, type = duration())
#> Error:
#> ! NotImplemented: Extend
{code}
Nevertheless, the fallback to creating an integer was unexpected.
Also, not sure if this is a bug, an improvement or a new feature.
