R is a free statistical, graphing and data management software. Unfortunately, R is very hard to learn. To bridge the gap between authoritative (but expensive) reference textbooks and free but often technical and difficult to understand help files, I created R Instructor. R Instructor is an Android and iPhone, iPad and iPod Touch application that uses plain, non-technical language and over 30 videos to explain how to make and modify plots, manage data and conduct both parametric and non-parametric statistical tests. Each example includes a very brief description of the function or test, any statistical assumptions, how to structure your data, the appropriate R scripts and links to other free and online resources. An Android version is imminent. I'm always working on new videos and expanding the range of content in R Instructor. To learn more, view the video below or read a complete description on iTunes or Google Play .See what R Instructor users are saying! It beats the books. Smart and powerful app that will teach you basic R commands. Not a word is wasted. Clear, well organized, and easy to navigate. Probably the best introductory resource to R I've come across, anywhere. Dr Bulbulia ★★★★★ (February 9, 2013) Brilliant quick reference and learning tool for R. Terrific. R Instructor's top-down, hierarchical organization of material makes it truly easy to find your category (e.g. plotting) then drill down to the aspect you want detail about. The detail is pared down brilliantly: syntax, explanation, assumptions where relevant and examples are concise and to the point. I found answers in minutes I had not found elsewhere in hours. Ronyon Onyon, ★★★★★ (December 1, 2012) A very practical tool. No R user should be without it Rolf Marvin Bøe Lindgren, ★★★★★ (Sept 5, 2012) I have found this app very useful. I really like the integration of short instructional videos. The developer replies immediately to emails and is incredibly helpful. Good stuff. InsectMick, ★★★★★ (July 2, 2012) Great App! This app is really handy, I've had it for like two hours and I must have used it 10 times already. Great app! [...] Thanks for this!!! Stat101, ★★★★★ (June 5, 2012) Awesome. This is awesome, exactly what I needed to help me learn R. Echristenson, ★★★★★ (May 31, 2012) |
