R: Convert an argument to an integer

asInteger {checkmate}

R Documentation

Convert an argument to an integer

Description

asInteger is intended to be used for vectors while asInt is a specialization for scalar integers and asCount for scalar non-negative integers. Convertible are (a) atomic vectors with all elements NA and (b) double vectors with all elements being within tol range of an integer.

Usage

asInteger(x, ..., tol = sqrt(.Machine$double.eps), .var.name)

asCount(x, na.ok = FALSE, positive = FALSE,
  tol = sqrt(.Machine$double.eps), .var.name)

asInt(x, na.ok = FALSE, lower = -Inf, upper = Inf,
  tol = sqrt(.Machine$double.eps), .var.name)

Arguments

`x`	[any] Object to convert.
`...`	[any] Additional arguments passed to `assertIntegerish`.
`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 for `x`. Defaults to a heuristic to determine the name using `deparse` and `substitute`.
`na.ok`	[`logical(1)`] Are missing values allowed? Default is `FALSE`.
`positive`	[`logical(1)`] Must `x` be positive (>= 1)? 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.

Value

Converted x.

Examples

asInteger(c(1, 2, 3))
asCount(1)
asInt(1)
