checkInteger

Check if an argument is vector of type integer

Description

Check if an argument is vector of type integer

Usage

checkInteger(
  x,
  lower = -Inf,
  upper = Inf,
  any.missing = TRUE,
  all.missing = TRUE,
  len = NULL,
  min.len = NULL,
  max.len = NULL,
  unique = FALSE,
  sorted = FALSE,
  names = NULL,
  null.ok = FALSE
)

  x,
  lower = -Inf,
  upper = Inf,
  any.missing = TRUE,
  all.missing = TRUE,
  len = NULL,
  min.len = NULL,
  max.len = NULL,
  unique = FALSE,
  sorted = FALSE,

)

  max.len = NULL,
  unique = FALSE,
  sorted = FALSE,

)

expect_integer(
  x,
  lower = -Inf,
  upper = Inf,
  any.missing = TRUE,

Arguments

`x`	[any] Object to check.
`lower`	[`numeric(1)`] Lower value all elements of `x` must be greater than or equal to.
`upper`	[`numeric(1)`] Upper value all elements of `x` must be lower than or equal to.
`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`.
`sorted`	[`logical(1)`] Elements must be sorted in ascending order. Missing values are ignored.
`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.
`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 assertInteger/assert_integer return x invisibly, whereas checkInteger/check_integer and testInteger/test_integer return TRUE. If the check is not successful, assertInteger/assert_integer throws an error message, testInteger/test_integer returns FALSE, and checkInteger returns a string with the error message. The function expect_integer always returns an expectation.

Examples

testInteger(1L)
testInteger(1.)
testInteger(1:2, lower = 1, upper = 2, any.missing = FALSE)
