Rcrawler - An R web crawler and scraper

  •    R

Rcrawler is an R package for web crawling websites and extracting structured data which can be used for a wide range of useful applications, like web mining, text mining, web content mining, and web structure mining. So what is the difference between Rcrawler and rvest : rvest extracts data from one specific page by navigating through selectors. However, Rcrawler automatically traverses and parse all web pages of a website, and extract all data you need from them at once with a single command. For example collect all published posts on a blog, or extract all products on a shopping website, or gathering comments, reviews for your opinion mining studies. More than that, Rcrawler can help you studies web site structure by building a network representation of a website internal and external hyperlinks (nodes & edges). Help us improve Rcrawler by asking questions, revealing issues, suggesting new features. If you have a blog write about it, or just share it with your collegues.
