Reading posts

• New reading posted, note that we're using the stats-based textbook now

• The count of question and answer posts has reset for the second half of the semester

• 5 question posts (2 questions each), 5 answer posts (1 answer each)

Homework

• Homework 2 grades were posted last week, remember, that you are permitted to revise and resubmit one assignment during the semester

• Resubmission needs to be in within one week of receiving your grade

• If you receive your grade late due to submission/technical issues, the 1 week count begins from when you receive the updated grade

• You won't be able to open a new Pull Request, so after commiting your revised files just go into the existing Pull Request, post Resubmission at the bottom, and tag myself and the grader

General

• Although we're shifting away from data wrangling as our main topic, we will continue to use tidyverse up until the end of the class

• Cumulative concepts, be sure to review if you're feeling rusty

• Cheat sheets are your friend! On http://fall.cds101.com, click Toolbox.

• Allows you to combine tables of related data.

• Very similar to joins using SQL
