Digital Data Collection course

Another year, another web scraping course. Taught through SSRMC at the University of Cambridge. Below are slides from all three sessions.

In the course I tried to achieve the following:
- Show how to connect R to resources online
- Use loops and functions to iteratively access online content
- How to work with APIs
- How to harvest data manually using Xpath expressions.

What's new?
- Many more examples and practice tasks
- Updated API usage
- Some bug fixes (and probably many new bugs introduced)




Slides from last year's course:
- session one: the basics
- session two: digging deeper
- session three: scaling up
- session four: APIs
