Check if an argument is disjunct from a given set
checkDisjunct(x, y, fmatch = FALSE)
check_disjunct(x, y, fmatch = FALSE)
assertDisjunct(x, y, fmatch = FALSE, .var.name = vname(x), add = NULL)
assert_disjunct(x, y, fmatch = FALSE, .var.name = vname(x), add = NULL)
testDisjunct(x, y, fmatch = FALSE)
test_disjunct(x, y, fmatch = FALSE)
expect_disjunct(x, y, fmatch = FALSE, info = NULL, label = vname(x))[any]
Object to check.
[atomic]
Other Set.
[logical(1)]
Use the set operations implemented in fmatch in package fastmatch.
If fastmatch is not installed, this silently falls back to match.
fmatch modifies y by reference:
A hash table is added as attribute which is used in subsequent calls.
[character(1)]
Name of the checked object to print in assertions. Defaults to
the heuristic implemented in vname.
[AssertCollection]
Collection to store assertion messages. See AssertCollection.
[character(1)]
Extra information to be included in the message for the testthat reporter.
See expect_that.
[character(1)]
Name of the checked object to print in messages. Defaults to
the heuristic implemented in vname.
Depending on the function prefix:
If the check is successful, the functions
assertDisjunct/assert_disjunct return
x invisibly, whereas
checkDisjunct/check_disjunct and
testDisjunct/test_disjunct return
TRUE.
If the check is not successful,
assertDisjunct/assert_disjunct
throws an error message,
testDisjunct/test_disjunct
returns FALSE,
and checkDisjunct/check_disjunct
return a string with the error message.
The function expect_disjunct always returns an
expectation.
The object x must be of the same type as the set w.r.t. typeof.
Integers and doubles are both treated as numeric.
