Harvesting Listicles

Scrape website data with the new R package rvest by hkitson@zevross.com.

From the post:

Copying tables or lists from a website is not only a painful and dull activity but it’s error prone and not easily reproducible. Thankfully there are packages in Python and R to automate the process. In a previous post we described using Python’s Beautiful Soup to extract information from web pages. In this post we take advantage of a new R package called rvest to extract addresses from an online list. We then use ggmap to geocode those addresses and create a Leaflet map with the leaflet package. In the interest of coding local, we opted to use, as the example, data on wineries and breweries here in the Finger Lakes region of New York.

Lists and listicles are a common form of web content. Unfortunately, both are difficult to improve without harvesting the content and recasting it.

This post will put you on the right track to harvesting with rvest!

BTW, as a benefit to others, post data that you clean/harvest in a clean format. Yes?
