Slides and links
Slides available on slideshare
Notes and and some links from the slides
- Jack Handey’s Deep Thoughts were a Saturday Night Live thing, many moons ago
- Emacs Speaks Statistics (ESS) manual. ESS + Emacs is still a great way to work with R, especially if you want one editor/IDE to cover other (non-R) languages. I used ESS before eventually switching to RStudio. Still waiting for the Emacs key-bindings :(
- Vince Buffalo tweet re: “write code for humans, write data for computers”. Apparently he also uses the phrase in his upcoming book Bioinformatics Data Skills.
- Tweet by
@jiffyclubillustrating agony of working with data formatted for human eyeballs- his iPython notebook
- data he was working with from California’s Department of Water Resources Data Exchange Center
- The International Obfuscated C Code Contest
- swirl: “a software package for the R programming language that turns the R console into an interactive learning environment”
For R novices
Work through: R basics, workspace and working directory, RStudio projects
For those familiar with R
Check out swirl. Work through one or more interactive courses with the goal of writing a short review (include in homework?). Feeling more ambitious? Check out swirlify and create a new lesson. I’d be happy to help think up topics.
