In gbRd: Utilities for processing Rd objects and files

Description

Extract help descriptions of one or more arguments of a function and return them as a string.

Usage

Rdo_args2txt(rdo, arg, title = "Hhh", name = "Aa", type = "text")

Arguments

rdo	the documentation for the topic, typically an Rd object but may be anything that Rd_fun accepts: Rd object, name of a function, or the value returned by help.
arg	name(s) of argument(s) to describe, a character vector, see also Details section
title	Title, a string
name	name, a string
type	type of the help, defaults to "text"

Details

The title and name fields are there, since descriptions of arguments usually do not use the same header as the description of the corresponding function.

The current defaults show that this is still not finished.

Value

A string (character vector of length one).
