Homework
- HW01: marking done. I’m sorting out a technical difficulty re: bulk emailing.
- HW02: Peer review done. TA marking underway.
- HW03: Due sometime today. Peer review will be set in motion this evening.
- HW04: Will be due … Tuesday October 13 at the earliest but likely later that week. Due to the Thanksgiving holiday and the way the topics are unfolding. I still want it to be about writing functions and split-apply-combine, but we may need a bit more time. Here’s the 2014 version but I might not do plyr this year.
Data life is not all rainbows and data.frames, so today we talk about R data structures.
- R objects (beyond data.frames) and indexing
Maybe we will even start to look at writing functions today?
- Write your own R functions, part 1
What’s coming?
- more dplyr: split-apply-combine, joins
- more writing your own functions
- tidy data

I will show some slides and put them here.
