In dplyr: A Grammar of Data Manipulation

coalesce() gives meaningful error messages

Code
  coalesce(1:2, 1:3)
Condition
  Error in `coalesce()`:
  ! Can't recycle `..1` (size 2) to match `..2` (size 3).

Code
  coalesce(1:2, letters[1:2])
Condition
  Error in `coalesce()`:
  ! Can't combine `..1` <integer> and `..2` <character>.

.size overrides the common size

Code
  coalesce(x, 1:2, .size = vec_size(x))
Condition
  Error in `coalesce()`:
  ! Can't recycle `..2` (size 2) to size 1.

can't be empty

Code
  coalesce()
Condition
  Error in `coalesce()`:
  ! `...` can't be empty.

must have at least one non-NULL vector

Code
  coalesce(NULL, NULL)
Condition
  Error in `coalesce()`:
  ! `...` must contain at least 1 non-`NULL` value.

inputs must be vectors

Code
  coalesce(1, environment())
Condition
  Error in `coalesce()`:
  ! `..2` must be a vector, not an environment.

names in error messages are indexed correctly

Code
  coalesce(1, "x")
Condition
  Error in `coalesce()`:
  ! Can't combine `..1` <double> and `..2` <character>.

Code
  coalesce(1, y = "x")
Condition
  Error in `coalesce()`:
  ! Can't combine `..1` <double> and `y` <character>.

Code
  coalesce(1:2, 1:3)
Condition
  Error in `coalesce()`:
  ! Can't recycle `..1` (size 2) to match `..2` (size 3).

Code
  coalesce(1:2, y = 1:3)
Condition
  Error in `coalesce()`:
  ! Can't recycle `..1` (size 2) to match `y` (size 3).

Code
  coalesce(1, NULL, "x")
Condition
  Error in `coalesce()`:
  ! Can't combine `..1` <double> and `..3` <character>.

Code
  coalesce(1, NULL, y = "x")
Condition
  Error in `coalesce()`:
  ! Can't combine `..1` <double> and `y` <character>.

Code
  coalesce(1:2, NULL, 1:3)
Condition
  Error in `coalesce()`:
  ! Can't recycle `..1` (size 2) to match `..3` (size 3).

Code
  coalesce(1:2, NULL, y = 1:3)
Condition
  Error in `coalesce()`:
  ! Can't recycle `..1` (size 2) to match `y` (size 3).
