[any]
Object to check.

Other Set.

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
The object x
must be of the same type as the set w.r.t. typeof
.
Integers and doubles are both treated as numeric.
