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.

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.
