Homework
- HW01: marking almost done. We will email you a mark for your HW and your peer reviews. Assuming you gave me a valid email address in the survey…. Hmmm, are you better at typing email addresses than GitHub usernames? We’ll see!
- HW02: Peer review underway. Try to do that today. Marking will start almost immediately – we want the feedback cycle to be faster.
- 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 did this Tuesday
- Part 2: dplyr functions for a single dataset doing this today
Data life is not all rainbows and data.frames, so we need to talk about R data structures.
- R objects (beyond data.frames) and indexing doing some of this today, finish on your own and ask me if you want more!
What’s coming?
- more dplyr
- Functions, split-apply-combine operations in general
- Tidy data

no slides planned
