testSubset: assert/check/test/Subset

In xoopR/set6: R6 Mathematical Sets Interface

assert/check/test/Subset

Description

Validation checks to test if given sets are subsets of a set.

Usage

testSubset(
  object,
  sets,
  proper = FALSE,
  errormsg = "sets are not subsets of the object"
)

checkSubset(
  object,
  sets,
  proper = FALSE,
  errormsg = "sets are not subsets of the object"
)

assertSubset(
  object,
  sets,
  proper = FALSE,
  errormsg = "sets are not subsets of the object"
)

Arguments

object	object to test
sets	sets to check
proper	logical. If TRUE tests for proper subsets.
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

testSubset(Set$new(1,2,3), Set$new(1,2))
testSubset(Set$new(1,2,3), Set$new(3,4))
