LinkExtractor {rNOMADS}

Extracts links from web pages

Description

Parse a web page, capturing and returning any links found.

Usage

LinkExtractor(url)

Arguments

url

A URL to scan for links.

Details

This is an internal routine used by several functions in the package.

Value

links

A vector of link URLs

Note

While it might be fun to try LinkExtractor on a large website such as Google, the results will be unpredictable and perhaps disastrous if depth is not set. This is because there is no protection against infinite recursion.
