Nicola Crane created ARROW-16447:
------------------------------------
Summary: [R] Integer overflow causes error - (in dplyr we get an
NA with a warning)
Key: ARROW-16447
URL: https://issues.apache.org/jira/browse/ARROW-16447
Project: Apache Arrow
Issue Type: Bug
Components: R
Reporter: Nicola Crane
{code:java}
library(dplyr)
library(arrow)
.input = tibble::tibble(
x = .Machine$integer.max
)
# in dplyr
.input %>%
mutate(x2 = x + 6L) %>%
collect()
#> Warning in x + 6L: NAs produced by integer overflow
#> # A tibble: 1 × 2
#> x x2
#> <int> <int>
#> 1 2147483647 NA
# in Arrow via arrow
.input %>%
arrow_table() %>%
mutate(x2 = x + 6L) %>%
collect()
#> Error in `collect()`:
#> ! Invalid: overflow

{code}
Do we want to enable the return of NAs on integer overflow, or just give the
user a more specific hint in the error message?
