Ho to rename tibble's .name_repair columns with dplyr

dpprdan · February 22, 2019, 8:57am

How do I rename columns with the new ..-type names that may result from tibble’s .name_repair?

x <- tibble::as_tibble(list(1), .name_repair = "unique")
#> New names:
#> * `` -> `..1`
dplyr::rename(x, a = `..1`)
#> Error in .f(.x[[i]], ...): ..1 used in an incorrect context, no ... to look in

Am I missing something, or is this a bug?

Make ...j the standard disambiguating suffix in name repair

I think we should go ahead and use `...j` as the standard suffix when `.name_rep…air = "unique"`. These names don't *have* to be syntactic but it's so easy to make them so (they are already ugly and have lots of dots) and it will reduce the downstream burden of dealing with non-syntactic names (example: https://github.com/tidyverse/dplyr/issues/4094). This would be good to do ASAP I think in a tiny release. What do you think @krlmlr?

The problem with ..1 and ... (and also with ``) is that these names not only not syntactic, they're invalid even as a quoted name.
