Nicola Crane commented on ARROW-17779:
--------------------------------------
OK, a few different things going on here:
# If you're using the release version of Arrow (9.0.0), using across() inside
summarise() isn't supported yet
# If you're using the dev version of Arrow which does support across() inside
summarise(), we don't yet have support for user-defined functions (ARROW-17366
covers lambda functions but I'll add something in now to also mention anonymous
functions)
Those things said, I wonder if we can update the error messaging here to be
more descriptive.
