In hadley/dplyr: A Grammar of Data Manipulation

with rowwise() data, leaves list-cols unwrapped (#5951, #6264)

Code
  mutate(rdf, z = pick(x, y))
Condition
  Error in `mutate()`:
  i In argument: `z = pick(x, y)`.
  i In row 2.
  Caused by error:
  ! `z` must be size 1, not 2.
  i Did you mean: `z = list(pick(x, y))` ?

Code
  mutate(rdf, z = pick_wrapper(x, y))
Condition
  Error in `mutate()`:
  i In argument: `z = pick_wrapper(x, y)`.
  i In row 2.
  Caused by error:
  ! `z` must be size 1, not 2.
  i Did you mean: `z = list(pick_wrapper(x, y))` ?

can't explicitly select grouping columns (#5460)

Code
  mutate(gdf, y = pick(g))
Condition
  Error in `mutate()`:
  i In argument: `y = pick(g)`.
  Caused by error in `pick()`:
  ! Can't select columns that don't exist.
  x Column `g` doesn't exist.

Code
  mutate(gdf, y = pick_wrapper(g))
Condition
  Error in `mutate()`:
  i In argument: `y = pick_wrapper(g)`.
  i In group 1: `g = 1`.
  Caused by error in `pick()`:
  ! Can't select columns that don't exist.
  x Column `g` doesn't exist.

must supply at least one selector to pick()

Code
  mutate(df, y = pick())
Condition
  Error in `mutate()`:
  i In argument: `y = pick()`.
  Caused by error in `pick()`:
  ! Must supply at least one input to `pick()`.

Code
  mutate(df, y = pick_wrapper())
Condition
  Error in `mutate()`:
  i In argument: `y = pick_wrapper()`.
  Caused by error in `pick()`:
  ! Must supply at least one input to `pick()`.

the tidyselection and column extraction are evaluated on the current data

Code
  mutate(gdf, x = NULL, y = pick(x))
Condition
  Error in `mutate()`:
  i In argument: `y = pick(x)`.
  Caused by error in `pick()`:
  ! Can't select columns that don't exist.
  x Column `x` doesn't exist.

Code
  mutate(gdf, x = NULL, y = pick_wrapper(x))
Condition
  Error in `mutate()`:
  i In argument: `y = pick_wrapper(x)`.
  i In group 1: `g = 1`.
  Caused by error in `pick()`:
  ! Can't select columns that don't exist.
  x Column `x` doesn't exist.

can call pick() from a user defined function

Code
  mutate(gdf, d = my_pick())
Condition
  Error in `mutate()`:
  i In argument: `d = my_pick()`.
  i In group 1: `a = 1`.
  Caused by error in `pick()`:
  i In argument: `all_of(x)`.
  Caused by error in `all_of()`:
  ! Can't subset elements that don't exist.
  x Element `a` doesn't exist.

Code
  mutate(gdf, d = my_pick(y))
Condition
  Error in `mutate()`:
  i In argument: `d = my_pick(y)`.
  i In group 1: `a = 1`.
  Caused by error in `pick()`:
  i In argument: `all_of(x)`.
  Caused by error in `all_of()`:
  ! Can't subset elements that don't exist.
  x Element `a` doesn't exist.

errors correctly outside mutate context

Code
  pick()
Condition
  Error in `pick()`:
  ! Must only be used inside data-masking verbs like `mutate()`, `filter()`, and `group_by()`.

Code
  pick(a, b)
Condition
  Error in `pick()`:
  ! Must only be used inside data-masking verbs like `mutate()`, `filter()`, and `group_by()`.

when expansion occurs, error labels use the pre-expansion quosure

Code
  mutate(df, if (cur_group_id() == 1L) pick(x) else "x", .by = g)
Condition
  Error in `mutate()`:
  i In argument: `if (cur_group_id() == 1L) pick(x) else "x"`.
  Caused by error:
  ! `if (cur_group_id() == 1L) pick(x) else "x"` must return compatible vectors across groups.
  i Result of type <tbl_df<x:double>> for group 1: `g = 1`.
  i Result of type <character> for group 2: `g = 2`.

doesn't allow renaming

Code
  mutate(data.frame(x = 1), pick(y = x))
Condition
  Error in `mutate()`:
  i In argument: `pick(y = x)`.
  Caused by error in `pick()`:
  ! Can't rename variables in this context.

Code
  mutate(data.frame(x = 1), pick_wrapper(y = x))
Condition
  Error in `mutate()`:
  i In argument: `pick_wrapper(y = x)`.
  Caused by error in `pick()`:
  ! Can't rename variables in this context.

pick() errors in arrange() are useful

Code
  arrange(df, pick(y))
Condition
  Error in `arrange()`:
  i In argument: `..1 = pick(y)`.
  Caused by error in `pick()`:
  ! Can't select columns that don't exist.
  x Column `y` doesn't exist.

Code
  arrange(df, foo(pick(x)))
Condition
  Error in `arrange()`:
  i In argument: `..1 = foo(pick(x))`.
  Caused by error in `foo()`:
  ! could not find function "foo"

filter() with pick() that uses invalid tidy-selection errors

Code
  filter(df, pick(x, a))
Condition
  Error in `filter()`:
  i In argument: `pick(x, a)`.
  Caused by error in `pick()`:
  ! Can't select columns that don't exist.
  x Column `a` doesn't exist.

Code
  filter(df, pick_wrapper(x, a))
Condition
  Error in `filter()`:
  i In argument: `pick_wrapper(x, a)`.
  Caused by error in `pick()`:
  ! Can't select columns that don't exist.
  x Column `a` doesn't exist.

filter() that doesn't use pick() result correctly errors

Code
  filter(df, pick(x, y)$x)
Condition
  Error in `filter()`:
  i In argument: `asNamespace("dplyr")$dplyr_pick_tibble(x = x, y = y)$x`.
  Caused by error:
  ! `..1` must be a logical vector, not a double vector.

Code
  filter(df, pick_wrapper(x, y)$x)
Condition
  Error in `filter()`:
  i In argument: `pick_wrapper(x, y)$x`.
  Caused by error:
  ! `..1` must be a logical vector, not a double vector.
