join_for_links: Join an ECOS table of text with the links to documents

In jacob-ogre/ecosscraper: Tools to Scrape the ECOS Website, http://ecos.fws.gov

Description

Extracting tables with links in cells using rvest isn't straight-forward. But by listing the links with html_nodes(..., "href") and the link text with html_text(...) (i.e., the link title), then joining with the table Title field, we can associate every doc link with the other fields in the table.

Usage

join_for_links(tab, links, species)

Arguments

tab	The table (as a data.frame) to be joined if it has a Title var
links	A data.frame with the Title of the link and the URL
species	The scientific name to be included in the returned data.frame

Value

A data.frame with URL, if tab includes a Title variable
