########## r/NEWS.md: ########## @@ -19,6 +19,9 @@ # arrow 16.0.0.9000 +* R functions that users write that use functions that Arrow supports in dataset queries now can be used in queries too. Previously, only functions that used arithmetic operators worked. For example, `time_hours <- function(mins) mins / 60` worked, but `time_hours_rounded <- function(mins) round(mins / 60)` did not; now both work. These are not true user-defined functions (UDFs); for those, see `register_scalar_function()`. (#41223) Review Comment: Late to looking at this but maybe the specifics around this can be documented better in user-facing help pages. If there are "true UDFs" (which these aren't), what would we call these? Further, it looks like this doesn't pull the data into R, is my read correct? -- This is an automated message from the Apache Git Service.
