testSet {set6} | R Documentation

## assert/check/test/Set

### Description

Validation checks to test if a given object is an R6 `Set`.

### Usage

    testSet(object, errormsg = "This is not an R6 Set object")

    checkSet(object, errormsg = "This is not an R6 Set object")

    assertSet(object, errormsg = "This is not an R6 Set object")

### Arguments

`object` | object to test
`errormsg` | error message to overwrite default if check fails

### Value

If check passes then `assert` returns `object` invisibly and `test`/`check` return `TRUE`. If check fails, `assert` stops code with error, `check` returns an error message as string, and `test` returns `FALSE`.

### Examples

    testSet(Set$new(2, 3))
    testSet(list(Set$new(2), Set$new(3)))
    testSet(Tuple$new(2, 3))
    testSet(Interval$new())
    testSet(FuzzySet$new(2, 0.1))
    testSet(FuzzyTuple$new(2, 0.1))
    testSet(ConditionalSet$new(function(x) x == 0))
