every(), some(), and none() require logical scalar predicate results

Code
  every(list(1), function(x) 1)
Condition
  Error in `every()`:
  ! `.p()` must return a single `TRUE`, `FALSE`, or `NA`, not the number 1.

Code
  some(list(1), function(x) 1)
Condition
  Error in `some()`:
  ! `.p()` must return a single `TRUE`, `FALSE`, or `NA`, not the number 1.

Code
  none(list(1), function(x) 1)
Condition
  Error in `none()`:
  ! `.p()` must return a single `TRUE`, `FALSE`, or `NA`, not the number 1.

Code
  every(list(1), function(x) NA_integer_)
Condition
  Error in `every()`:
  ! `.p()` must return a single `TRUE`, `FALSE`, or `NA`, not an integer `NA`.

Code
  some(list(1), function(x) NA_integer_)
Condition
  Error in `some()`:
  ! `.p()` must return a single `TRUE`, `FALSE`, or `NA`, not an integer `NA`.

Code
  none(list(1), function(x) NA_integer_)
Condition
  Error in `none()`:
  ! `.p()` must return a single `TRUE`, `FALSE`, or `NA`, not an integer `NA`.

Code
  every(list(1), function(x) c(TRUE, FALSE))
Condition
  Error in `every()`:
  ! `.p()` must return a single `TRUE`, `FALSE`, or `NA`, not a logical vector.

Code
  some(list(1), function(x) c(TRUE, FALSE))
Condition
  Error in `some()`:
  ! `.p()` must return a single `TRUE`, `FALSE`, or `NA`, not a logical vector.

Code
  none(list(1), function(x) c(TRUE, FALSE))
Condition
  Error in `none()`:
  ! `.p()` must return a single `TRUE`, `FALSE`, or `NA`, not a logical vector.

every(), some(), and none() require vector `.x`

Code
  every(function() 1, identity)
Condition
  Error in `every()`:
  ! `.x` must be a vector, not a function.

Code
  some(function() 1, identity)
Condition
  Error in `some()`:
  ! `.x` must be a vector, not a function.

Code
  none(function() 1, identity)
Condition
  Error in `none()`:
  ! `.x` must be a vector, not a function.

pairlists, expressions, and calls are deprecated but work

Code
  out <- every(expression(1, 2), is.double)
Condition

  i Please coerce explicitly with `as.list()`

Code

Code
