checkIntegerish: Check if an object is an integerish vector

Description

An integerish value is defined as value safely convertible to integer. This includes integers and numeric values which are close to an integer w.r.t. a numeric tolerance.

Usage

checkIntegerish(x, tol = sqrt(.Machine$double.eps), lower = -Inf,
  upper = Inf, any.missing = TRUE, all.missing = TRUE, len = NULL,
  min.len = NULL, max.len = NULL, unique = FALSE, sorted = FALSE,
  names = NULL, null.ok = FALSE)
check_integerish(x, tol = sqrt(.Machine$double.eps), 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)
assertIntegerish(x, tol = sqrt(.Machine$double.eps), lower = -Inf,
  upper = Inf, any.missing = TRUE, all.missing = TRUE, len = NULL,
  min.len = NULL, max.len = NULL, unique = FALSE, sorted = FALSE,
  names = NULL, null.ok = FALSE, .var.name = vname(x), add = NULL)
assert_integerish(x, tol = sqrt(.Machine$double.eps), 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, .var.name = vname(x), add = NULL)
testIntegerish(x, tol = sqrt(.Machine$double.eps), lower = -Inf,
  upper = Inf, any.missing = TRUE, all.missing = TRUE, len = NULL,
  min.len = NULL, max.len = NULL, unique = FALSE, sorted = FALSE,
  names = NULL, null.ok = FALSE)
test_integerish(x, tol = sqrt(.Machine$double.eps), 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)
expect_integerish(x, tol = sqrt(.Machine$double.eps), 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, info = NULL, label = vname(x))

Arguments

x

[any] Object to check.

tol

[double(1)] Numerical tolerance used to check whether a double or complex can be converted. Default is sqrt(.Machine$double.eps).

lower

[numeric(1)] Lower value all elements of x must be greater than.

upper

[numeric(1)] Upper value all elements of x must be lower than.

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.

Value

Depending on the function prefix: If the check is successful, the functions assertIntegerish/assert_integerish return x invisibly, whereas checkIntegerish/check_integerish and testIntegerish/test_integerish return TRUE. If the check is not successful, assertIntegerish/assert_integerish throws an error message, testIntegerish/test_integerish returns FALSE, and checkIntegerish returns a string with the error message. The function expect_integerish always returns an expectation.

Details

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