Check if an argument is a vector of type logical

Description

Check if an argument is a vector of type logical

Usage

  any.missing = TRUE,
  all.missing = TRUE,
  len = NULL,
  min.len = NULL,
  max.len = NULL,
  unique = FALSE,
  names = NULL,
  typed.missing = FALSE,
  null.ok = FALSE
)

  null.ok = FALSE,
  .var.name = vname(x),

)

Arguments

x	[any] Object to check.
any.missing	[logical(1)] Are vectors with missing values allowed? Default is TRUE.
all.missing	[logical(1)] Are vectors with no non-missing values allowed? Default is TRUE. Note that empty vectors do not have non-missing values.
len	[integer(1)] Exact expected length of x.
min.len	[integer(1)] Minimal length of x.
max.len	[integer(1)] Maximal length of x.
unique	[logical(1)] Must all values be unique? Default is FALSE.
names	[character(1)] Check for names. See checkNamed for possible values. Default is “any” which performs no check at all. Note that you can use checkSubset to check for a specific set of names.
typed.missing	[logical(1)] If set to FALSE (default), all types of missing values (NA, NA_integer_, NA_real_, NA_character_ or NA_character_) as well as empty vectors are allowed while type-checking atomic input. Set to TRUE to enable strict type checking.
null.ok	[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.
.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.

Details

This function does not distinguish between NA, NA_integer_, NA_real_, NA_complex_ NA_character_ and NaN.

Value

Depending on the function prefix: If the check is successful, the functions assertLogical/assert_logical return x invisibly, whereas checkLogical/check_logical and testLogical/test_logical return TRUE. If the check is not successful, assertLogical/assert_logical throws an error message, testLogical/test_logical returns FALSE, and checkLogical/check_logical return a string with the error message. The function expect_logical always returns an expectation.
