Lucas Mation created ARROW-18241: ------------------------------------ Summary: as.integer can't handdle empty character cels (ex c('')) Key: ARROW-18241 URL: https://issues.apache.org/jira/browse/ARROW-18241 Project: Apache Arrow Issue Type: Bug Reporter: Lucas Mation
I am importing a dataset with arrow, and then converting variable types. But I got an error message because the `arrow` implementation of `as.integer` can't handle empty strings (which is legal in base R). Is this a bug? ``` #In R '' %>% as.integer() [1] NA #in arrow q <- data.table(x=c('','1','2')) q %>% write_dataset(paste0(p2,'/q')) q2 <- paste0(p2,'/q') %>% open_dataset %>% mutate(x=as.integer(x)) %>% collect Error in `collect()`: ! Invalid: Failed to parse string: '' as a scalar of type int32 Run `rlang::last_error()` to see where the error occurred. ``` -- This message was sent by Atlassian Jira (v8.20.10#820010)
