add.argument

parser

argument name (use no prefix for positional arguments,
<code>--</code> or <code>-</code> prefix for optional arguments or flags)

help

default value for the argument [default: NA]

default

variable type of the argument (which can be inferred from 
<code>default</code>), assumed to be <code>character</code> otherwise

type

whether argument is a flag (and does not consume a value)
[default: FALSE]

flag

short-form for flags and positional arguments;
short-forms can be assigned automatically based on the first
character of the argument name, unless a conflict arises with
an existing short-form; to avoid conflicts, add the argument 
as early as possible

short

This function is deprecated. Use <code>add_argument</code> instead.

Cross-platform command-line argument parser written purely in R
with no external dependencies. It is useful with the Rscript
front-end and facilitates turning an R script into an executable script.
