R is a free statistical, visualisation and data manipulation software. Anyone who works with data can benefit from using R but it is hard to learn.
Created by scientist and educator Dr Shidan Murphy, R Instructor is a statistical and R reference guide. The application uses plain, non-technical language and over 35 succinct videos to guide new users and reinforce concepts for advanced R users. The number and scope of the videos and content will continue to increase.
R Instructor will teach you how to use R, how to make and modify plots and run statistical tests. Each example includes a very brief (and easy to understand!) description of the function or test, any statistical assumptions, how to structure your data in R, the R scripts (code) and, links to other free and online resources. Where appropriate, the Mac, Windows and RStudio versions of the R interface are explained separately.
R Instructor also allows you to run RStudio through the web from your iPad or iPhone (Note: This is a public server that requires an internet connection -- do not expect to accomplish serious computing)
In addition, R Instructor comes complete with 10 Quick Reference guides and the "Which Test?" feature. The "Which Test?" feature guides you to the correct statistical test after you answer questions related to your data.

R Instructor FAQ
Is R Instructor free?
R Instructor is not free (it costs 2.99), however it doesn't contain in-app purchases or subscriptions.
Is R Instructor legit?
✅ The R Instructor app appears to be high-quality and legitimate. Users are very satisfied.
Compared to the other three I bought that are useless, RStudio lets me study my old econometrics, follow nice implementations, get additional packages, and all under the same interface as in Mac. Kudos for RStudio and million thanks to its creator and maintainer Shidan Murphy. Joaquin Gutierrez.
Great application
I love the app. Simple interface, quick to the point cheat sheet for everyday analyses and some advanced concepts as well (such as PCA). It has a nice "which test" algorithm. Overall great app.
Very well done app!
Impressive. Well put together and organized. Worth the money. I’ve been wanting to learn R for a long time and this app presented the material in a way using code snippets that made learning easy.
Excellent Guide & Reference
This is an excellent guide and reference worth every penny. Within minutes I was able to import and plot Excel data. The user interface is well structured allowing quick access to specific topics. It can also be used as a tutorial by simply starting at the main page and progressing through the pages in order. There are many live links to outside resources.
I use this program as my regular "R" manual on my iPad. Contrary to one reviewer (who must have been having a very bad day) I find this program extremely useful.
Don't buy this. It's a total ripoff
There are about 15 or 20 slides with very few examples. You can learn this all free from Introduction menu on R console. After looking at this, I am so disappointed, that I wanted to claim Refund, right away (because it is unprofessional to ripoff our community with this type of zero-value apps). However, the app-maker has NOT provided any contact info. Don't buy this app.
Useful and Welcome
I do appreciate this app. There are many R resources around the web but very few that are handy to the iPhone. So this fills an important need. I use it frequently and find it useful. Please keep developing!
Thanks.
Fantastique
Great voice, nice videos, short summaries. Thanks!
R Instructor is great for learning R
R Instructor is great for learning R. If you are starting out with R or if you are already R, you will find something that is useful. I especially like the decisioin tree for assisting what type of statisical test you should do depending on your data.
Helpful introduction to R
I am finding the videos and reference material of the R Instructor app to be very useful as an introduction to R. I also like the "which test" guide as an aid to building my confidence with the statistics.
The RStudio server (yes, through Safari) is also useful for practice...using it now from my iPad.
Best stats app!!
This is an excellent application. This opens up many possibilities for performing statistics, it goes far beyond being a reference. R Instructor has many features to perform advanced stats, learn from the tutorials, and the instructor provides excellent customer service. I highly recommend this app!
