Links to previous Cape R User Group slides/seminars etc
Glenn Moncrieff on Leaflet / R / Shiny (on RPub)
Robert Schlegel with Shiny and the SA Coastal Temperature Network [links to come, wordpress irritating about file types]
Brian Peterson on Developing and backtesting Systematic trading strategies (YouTube) and slides
Jasper Slingsby on A Primer for Spatial Data Analysis in R (RPubs)
IDRE UCLA Statistical Computing have an amazing website full of annotated examples of standard analyses in R (and other software). If you need to know how to do a logistic regression or an ANOVA in R this is the first place to check. Really.
Great example of the shiny package in action, plus great examples of clean R figures to put in your next paper.
This is where I send people who have zero R experience.
First – the codeschool, it comes with badges and everything and you don’t even need to install R!
Then this coursera course (if it is running, and the individuals have time)
Then I suggest specific tutorials. List will go up soon.
