[any]
Object to check.
[atomic
]
Set to compare with.
[logical(1)
]
Check x
to have the same length and order as y
, i.e.
check using “==” while handling NA
s nicely.
Default is FALSE
.
[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
assertSubset
/assert_subset
return
x
invisibly, whereas
checkSubset
/check_subset
and
testSubset
/test_subset
return
TRUE
.
If the check is not successful,
assertSubset
/assert_subset
throws an error message,
testSubset
/test_subset
returns FALSE
,
and checkSubset
/check_subset
return a string with the error message.
The function expect_subset
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.
