(By Hadley Wickham) Hi all, I’d like to let you know about four R training courses that RStudio will be offering in December: * Effective data visualization (http://bit.ly/TY2ONI) Dec 3. San Francisco, CA * Reports and reproducible research (http://bit.ly/RsZmYr) Dec 4. San Francisco, CA * Advanced R programming (http://bit.ly/RvZDsd) Dec 10. Washington, DC * Package development (http://bit.ly/UhTIWz) Dec 11. Washington, DC In EFFECTIVE DATA VISUALISATION (http://bit.ly/TY2ONI), you’ll learn how to make beautiful, effective graphs using ggplot2 and the grammar of graphics. You’ll learn not only technical R skills, but also how the human perceptual system works. REPORTS AND REPRODUCIBLE RESEARCH (http://bit.ly/RsZmYr) will jump start your workflow for generating polished and reproducible publications and presentations from R research. You’ll learn how to use knitr to make scriptable pdf reports, html pages and slideshows, and general tips for making code that others can use and learn from. ADVANCED R PROGRAMMING (http://bit.ly/RvZDsd) will help you write better code, by focussing on the mantra of “do not repeat yourself”. You will learn powerful new tools of abstraction, allowing you to solve a wider range of problems with fewer lines of code. PACKAGE DEVELOPMENT (http://bit.ly/UhTIWz) will teach you how to make packages, the fundamental unit of code distribution in R, allowing others to save time by allowing them to use your code. We focus on tools (devtools, roxygen2, testthat) designed to make package development as easy as possible. Our courses incorporate a mix of lectures and hands-on learning. Expect to learn about a topic and then immediately put it into practice with a small example. Plenty of help will be available if you get stuck. You can read more about our training philosophy at http://www.rstudio.com/training/philosophy.html To see prices, precise locations and to register: * for the DC courses: http://rstudio-dc.eventbrite.com/ * for the SF courses: http://rstudio-sf.eventbrite.com/ We have limited discounts for students (66% off) and academics (33% off) – please contact me for details.
