checkmate (version 1.7.4)

checkInt: Check if an argument is a single integerish value

Description

Check if an argument is a single integerish value

Usage

checkInt(x, na.ok = FALSE, lower = -Inf, upper = Inf,
  tol = sqrt(.Machine$double.eps))
assertInt(x, na.ok = FALSE, lower = -Inf, upper = Inf,
  tol = sqrt(.Machine$double.eps), .var.name = vname(x), add = NULL)
assert_int(x, na.ok = FALSE, lower = -Inf, upper = Inf,
  tol = sqrt(.Machine$double.eps), .var.name = vname(x), add = NULL)
testInt(x, na.ok = FALSE, lower = -Inf, upper = Inf,
  tol = sqrt(.Machine$double.eps))
test_int(x, na.ok = FALSE, lower = -Inf, upper = Inf,
  tol = sqrt(.Machine$double.eps))
expect_int(x, na.ok = FALSE, lower = -Inf, upper = Inf,
  tol = sqrt(.Machine$double.eps), info = NULL, label = vname(x))

Arguments

x

[any] Object to check.

na.ok

[logical(1)] Are missing values allowed? Default is FALSE.

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.

tol

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

.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, assertInt/assert_int throws an error message, testInt/test_int returns FALSE, and checkInt returns a string with the error message. The function expect_int always returns an expectation.

Details

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