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, names = NULL)
assertInteger(x, lower = -Inf, upper = Inf, any.missing = TRUE,
  all.missing = TRUE, len = NULL, min.len = NULL, max.len = NULL,
  unique = FALSE, names = NULL, .var.name)
testInteger(x, lower = -Inf, upper = Inf, any.missing = TRUE,
  all.missing = TRUE, len = NULL, min.len = NULL, max.len = NULL,
  unique = FALSE, names = NULL)

Arguments

x

[ANY] Object to check.

.var.name

[character(1)] Name for x. Defaults to a heuristic to determine the name using deparse and substitute.

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.

Value

• Depending on the function prefix: If the check is successful, all functions return TRUE. If the check is not successful, assertInteger throws an error message, testInteger returns FALSE and checkInteger returns a string with the error message.

Details

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