All course communications should be posted on Campuswire; please direct all questions you have during the quarter either as a public post or to “instructors & TAs” there.
Next to each lecture below, “code” is the .Rmd file that makes the slides, and “write” is the pdf that will (more or less) be what I project in class, and that you can either print or download to take notes on. You can ignore the “code” file unless you are curious about how anything in the slides was created. Note: if you want to open it in a new tab, you can right-click and select “Open link in new tab” there; (I couldn’t figure out how to make it automatically open in a new tab with a left-click in this website theme).
