assert_integerish: Check if an argument is vector of type integer

In PetterHopp/NVIcheckmate: Extension of checkmate with argument checking adapted for NVIverse

Check if an argument is vector of type integer

Description

Check if an argument is vector of type integer.

Usage

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,
  typed.missing = FALSE,
  null.ok = FALSE,
  .var.name = checkmate::vname(x),
  comment = NULL,
  add = NULL
)

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 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 no non-missing values allowed? Default is TRUE. Note that empty vectors do not have non-missing values.
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.
typed.missing	[logical(1)] If set to FALSE (default), all types of missing values (NA, NA_integer_, NA_real_, NA_character_ or NA_character_) as well as empty vectors are allowed while type-checking atomic input. Set to TRUE to enable strict type checking.
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 error messages. Defaults to the heuristic implemented in vname.
comment	[character(1)] Extra information to be appended to the standard error message in assertions.
add	[AssertCollection] Collection to store assertions. See AssertCollection.

Details

The assertions are based on checkmate::checkIntegerish. NVIcheckmate::assert_integerish differs from checkmate::assert_integerish in including the argument comment = . The help is updated to reflect the changes.

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 function assert_Integerish return x invisibly, whereas check_Integerish return TRUE.
If the check is not successful, assert_Integerish throws an error message and check_Integerish returns a string with the error message.

If the check is successful, the function assert_integerish return x invisibly.
If the check is not successful, assert_integerish throws an error message.
