[any] Object to check.
[atomic
]
Set of possible values.
[logical(1)
]
If set to TRUE
, x
may also be NULL
.
In this case only a type check of x
is performed, all additional checks are disabled.
[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
assertChoice
/assert_choice
return
x
invisibly, whereas
checkChoice
/check_choice
and
testChoice
/test_choice
return
TRUE
.
If the check is not successful,
assertChoice
/assert_choice
throws an error message,
testChoice
/test_choice
returns FALSE
,
and checkChoice
returns a string with the error message.
The function expect_choice
always returns an
expectation
.
Other set:
checkDisjunct()
,
checkSetEqual()
,
checkSubset()
# NOT RUN {
testChoice("x", letters)
# x is not converted before the comparison (except for numerics)
testChoice(factor("a"), "a")
testChoice(1, "1")
testChoice(1, as.integer(1))
# }
