--------------------------------
Assignee: Ian Cook
> [R] transmute() fails after pulling data into R
> -----------------------------------------------
>
> Key: ARROW-13262
> URL: https://issues.apache.org/jira/browse/ARROW-13262
> Project: Apache Arrow
> Issue Type: Improvement
> Components: R
> Reporter: Jonathan Keane
> Assignee: Ian Cook
> Priority: Major
> Labels: pull-request-available
> Time Spent: 20m
> Remaining Estimate: 0h
>
> NOTE: This issue was originally named "[R] Support namespacing of function
> maps?". [~icook] renamed it to reflect the resolution described in the
> comments below.
> With our NSE function map setup, we translate various functions into Arrow
> equivalents:
> {code:java}
> library(arrow)
> library(dplyr)
> arrow_table <- Table$create(tibble::tibble(
> v = c("A", "B", "C"),
> w = c("a", "b", "c"),
> x = c("d", NA_character_, "f"),
> y = c(NA_character_, "h", "i"),
> z = c(1.1, 2.2, NA)
> ))
> arrow_table %>%
> transmute(str_c(x, y, sep = " ")) %>%
> collect()
> #> # A tibble: 3 x 1
> #> `str_c(x, y, sep = " ")`
> #> <chr>
> #> 1 <NA>
> #> 2 <NA>
> #> 3 f i
> {code}
> Which is great, however if the code that is being used uses the `sringr::`
> namespace prefix this errors:
> {code:java}
> arrow_table %>%
> transmute(stringr::str_c(x, y, sep = " ")) %>%
> collect()
> #> Warning: Expression stringr::str_c(x, y, sep = " ") not supported in Arrow;
> #> pulling data into R
> #> Error: Problem with `mutate()` input `..1`.
> #> ℹ `..1 = ..1`.
> #> x object 'x' not found
> {code}
> Should we support this (basically *also* translate {{stringr::str_c()}} to
> what we have for {{str_c()}})? Or warn/error more clearly what happened if we
> don't support any namespace prefixed functions? Something else?
