Week 9 Info: Webscraping and Hierarchical Data

Click here for info on Week 9

Hello Class,

Today is the start of week 9, where we will learn how to work with hierarchical data sets and how to use R to scrape websites for data. Web datasets are usually stored in a hierarchical, rather than tabular format, which requires different tools. We will make use of the rvest package to webscrape data into R and also use tools from the purrr package and data contained in repurrrsive.

This week we will have a lab assignment which involves extracting data stored in a hierarchical format, and combining webscraping tools with functions and iteration to automatically download many files at once. This assignment is due Sunday by midnight: Lab 7.

For your reading assignments and more details about this week, head over to Module 9. .
