Similar to checkNamed but you can pass the names directly.
Usage
checkNames(x, type = "named")
check_names(x, type = "named")
assertNames(x, type = "named", .var.name = vname(x), add = NULL)
assert_names(x, type = "named", .var.name = vname(x), add = NULL)
testNames(x, type = "named")
test_names(x, type = "named")
expect_names(x, type = "named", info = NULL, label = vname(x))
Arguments
x
[character || NULL]
Names to check using rules defined via type.
type
[character(1)]
Select the check(s) to perform.
“unnamed” checks x to be NULL.
“named” (default) checks x for regular names which excludes names to be NA or empty ("").
“unique” additionally tests for non-duplicated names.
“strict” checks for unique names which comply to R's variable name restrictions.
Note that you can use checkSubset to check for a specific set of names.
.var.name
[character(1)]
Name of the checked object to print in assertions. Defaults to
the heuristic implemented in vname.
add
[AssertCollection]
Collection to store assertion messages. See AssertCollection.
info
[character(1)]
Extra information to be included in the message for the testthat reporter.
See expect_that.
label
[character(1)]
Name of the checked object to print in messages. Defaults to
the heuristic implemented in vname.
Value
Depending on the function prefix:
If the check is successful, the functions return TRUE. If the check
is not successful, assertNamed/assert_named
throws an error message, testNamed/test_named
returns FALSE,
and checkNamed returns a string with the error message.
The function expect_named always returns an
expectation.
Examples
x = 1:3
testNames(x, "unnamed")
names(x) = letters[1:3]
testNames(x, "unique")
