Thanks @paleolimbot & @assignUser. I wouldn't have thought to look under "acero" for the docs but that's exactly what I needed. My guess is then that only the functions under the "Function mappings" header would be available inside `summarize`, `mutate`, etc, and `length`, `unique`, and `count_distinct` are not among them. I didn't know about `count` as a first class dplyr verb. TIL! Nor did I know about the convenience function `n_distinct`. I think this is what I need -- although it looks like what lead me astray was that the "Working with Arrow Datasets and dplyr" vignette doesn't include `count` in its list of supported dplyr verbs or contain a link to the https://arrow.apache.org/docs/r/reference/acero.html page. I'd be happy to submit a PR with some edits to the vignette if that would be helpful. -- This is an automated message from the Apache Git Service.
