checkmate (version 1.4)

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)
assertArray(x, mode = NULL, any.missing = TRUE, d = NULL, .var.name)
testArray(x, mode = NULL, any.missing = TRUE, d = NULL)

Arguments

x

[ANY] Object to check.

.var.name

[character(1)] Name for x. Defaults to a heuristic to determine the name using deparse and substitute.

mode

[character(1)] Storage mode of the matrix. Matricies can hold logical, integer, double, numeric, complex and character. Default is NUL

any.missing

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

d

[integer(1)] Dimensionality of array. Default is NULL (no check).

Value

• Depending on the function prefix: If the check is successful, all functions return TRUE. If the check is not successful, assertArray throws an error message, testArray returns FALSE and checkArray returns a string with the error message.
