• Homework
  • HW01: marking underway
  • HW02: we expect you to submit today; I’ll assign peer review issues tonight
  • HW03: will be due Tuesday 2015-10-06; here’s how it looked last year but give me a chance to refresh – Homework 3
• Hello dplyr!
  • Part 1: Introduction to dplyr
  • Part 2: dplyr functions for a single dataset
• Not sure I’ll get to it today, but you’re going to need this stuff soon. Feel free to start it on your own:
  • R objects (beyond data.frames) and indexing
• What’s coming? we’ll gradually move into this:
  • Functions, split-apply-combine
  • Tidy data
