checkmate (version 1.9.3)

checkAtomic: Check that an argument is an atomic vector

Description

For the definition of “atomic”, see is.atomic.

Usage

checkAtomic(x, any.missing = TRUE, all.missing = TRUE, len = NULL,
  min.len = NULL, max.len = NULL, unique = FALSE, names = NULL)
check_atomic(x, any.missing = TRUE, all.missing = TRUE, len = NULL,
  min.len = NULL, max.len = NULL, unique = FALSE, names = NULL)
assertAtomic(x, any.missing = TRUE, all.missing = TRUE, len = NULL,
  min.len = NULL, max.len = NULL, unique = FALSE, names = NULL,
  .var.name = vname(x), add = NULL)
assert_atomic(x, any.missing = TRUE, all.missing = TRUE, len = NULL,
  min.len = NULL, max.len = NULL, unique = FALSE, names = NULL,
  .var.name = vname(x), add = NULL)
testAtomic(x, any.missing = TRUE, all.missing = TRUE, len = NULL,
  min.len = NULL, max.len = NULL, unique = FALSE, names = NULL)
test_atomic(x, any.missing = TRUE, all.missing = TRUE, len = NULL,
  min.len = NULL, max.len = NULL, unique = FALSE, names = NULL)
expect_atomic(x, any.missing = TRUE, all.missing = TRUE, len = NULL,
  min.len = NULL, max.len = NULL, unique = FALSE, names = NULL,
  info = NULL, label = 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 only missing values allowed? Default is TRUE.

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.

.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 assertAtomic/assert_atomic return x invisibly, whereas checkAtomic/check_atomic and testAtomic/test_atomic return TRUE. If the check is not successful, assertAtomic/assert_atomic throws an error message, testAtomic/test_atomic returns FALSE, and checkAtomic returns a string with the error message. The function expect_atomic always returns an expectation.
