ensureVector

R Documentation

Blow up single scalars / objects to vectors / list by replication.

Description

Useful for standard argument conversion where a user can input a single element, but this has to be replicated now n times for a resulting vector or list.

Usage

ensureVector(x, n = 1L, cl = NULL, names = NULL, ensure.list = FALSE)

Arguments

`x`	[any] Input element.
`n`	[`integer(1)`] Desired length. Default is 1 (the most common case).
`cl`	[`character`*] Only do the operation if `x` inherits from this one of these classes, otherwise simply let `x` pass. Default is `NULL` which means to always do the operation.
`names`	[`character`*] Names for result. Default is `NULL`, which means no names.
`ensure.list`	[`logical(1)`] Should `x` be wrapped in a list in any case? Default is `FALSE`, i.e., if `x` is a scalar value, a vector is returned.
