checkNumeric: Check that an argument is a vector of type numeric

Description

Check that an argument is a vector of type numeric

Usage

checkNumeric(x, lower = -Inf, upper = Inf, finite = FALSE,
  any.missing = TRUE, all.missing = TRUE, len = NULL, min.len = NULL,
  max.len = NULL, unique = FALSE, names = NULL)

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

testNumeric(x, lower = -Inf, upper = Inf, finite = FALSE, 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.
finite
[logical(1)] Check for only finite values? Default is FALSE.
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, assertNumeric throws an error message, testNumeric returns FALSE and checkNumeric 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.
