Lucas Mation updated ARROW-18244:
---------------------------------
Description:
```
q <- data.table(x=c('','30111976','01011976'))
q %>% write_dataset('q')
q2 <- 'q' %>% open_dataset %>% mutate(x2=ifelse(x=='',NA,x)) %>% collect
Error in `collect()`:
! NotImplemented: Function 'if_else' has no kernel matching input types (bool,
bool, string)
Run `rlang::last_error()` to see where the error occurred.
```
In [Functions available in Arrow dplyr
queries|https://arrow.apache.org/docs/r/reference/acero.html] it is stated that
ifelse() is available, but the error above suggests otherwise.
Edit, "str_replace" is another function that is supposedly available in 10.0.0
but is not (or does not seem to be):
