In javifar/TIDYVERSE-DPLYR: A Grammar of Data Manipulation

selection works with grouped data frames (#2624)

Code
  out <- mutate_if(gdf, is.factor, as.character)
Message <message>
  `mutate_if()` ignored the following grouping variables:
  Column `Species`

colwise mutate gives meaningful error messages

Code
  mutate_at(tibble(), "test", ~1)
Error <vctrs_error_subscript_oob>
  Can't subset columns that don't exist.
  x Column `test` doesn't exist.

Code
  summarise_at(tbl, vars(gr1), mean)
Error <vctrs_error_subscript_oob>
  Can't subset columns that don't exist.
  x Column `gr1` doesn't exist.

Code
  mutate_all(mtcars, length, 0, 0)
Error <dplyr:::mutate_error>
  Problem with `mutate()` column `mpg`.
  i `mpg = .Primitive("length")(mpg, 0, 0)`.
  x 3 arguments passed to 'length' which requires 1

Code
  mutate_all(mtcars, mean, na.rm = TRUE, na.rm = TRUE)
Error <dplyr:::mutate_error>
  Problem with `mutate()` column `mpg`.
  i `mpg = (function (x, ...) ...`.
  x formal argument "na.rm" matched by multiple actual arguments
