checkArray: Check if an argument is an array

Description

Check if an argument is an array

Usage

checkArray(x, mode = NULL, any.missing = TRUE, d = NULL, min.d = NULL,
  max.d = NULL)
assertArray(x, mode = NULL, any.missing = TRUE, d = NULL, min.d = NULL,
  max.d = NULL, .var.name = vname(x), add = NULL)
assert_array(x, mode = NULL, any.missing = TRUE, d = NULL, min.d = NULL,
  max.d = NULL, .var.name = vname(x), add = NULL)
testArray(x, mode = NULL, any.missing = TRUE, d = NULL, min.d = NULL,
  max.d = NULL)
test_array(x, mode = NULL, any.missing = TRUE, d = NULL, min.d = NULL,
  max.d = NULL)
expect_array(x, mode = NULL, any.missing = TRUE, d = NULL, min.d = NULL,
  max.d = NULL, info = NULL, label = vname(x))

Arguments

x

[any] Object to check.

mode

[character(1)] Storage mode of the array. Arrays can hold vectors, i.e. logical, integer, double, numeric, complex, character and li

any.missing

[logical(1)] Are missing values allowed? Default is TRUE.

d

[integer(1)] Exact number of dimensions of array x. Default is NULL (no check).

min.d

[integer(1)] Minimum number of dimensions of array x. Default is NULL (no check).

max.d

[integer(1)] Maximum number of dimensions of array x. Default is NULL (no check).

.var.name

[character(1)] Name of the checked object to print in assertions. Defaults to the heuristic implemented in vname.

add

[AssertCollection] Collection to store assertion messages. See AssertCollection.

info

[character(1)] Extra information to be included in the message for the testthat reporter. See expect_that.

label

[character(1)] Name of the checked object to print in messages. Defaults to the heuristic implemented in vname.

Value

• Depending on the function prefix: If the check is successful, the functions return TRUE. If the check is not successful, assertArray/assert_array throws an error message, testArray/test_array returns FALSE, and checkArray returns a string with the error message. The function expect_array always returns an expectation.
