checkIntegerish: Check if an object is an integerish vector

Description

Check if an object is an integerish vector

Usage

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

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

.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, 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.
