R is a free statistical, graphing and data manipulation software. Anyone who works with data can benefit from using R, unfortunately it is very hard to learn.
Created by Dr. Shidan Murphy, an award-winning scientist and educator, R Instructor allows you to run RStudio through a web server from your iPad or iPhone (Note: This is a public server that requires an internet connection -- do not expect to accomplish serious computing) and teaches R using plain, non-technical language and over 30 videos (that's over two hours!). 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 comes complete with 10 Quick Reference guides and a comprehensive search feature so you can quickly learn more about a function.
**** As added bonus ****
Use our online forum to get help from other R Instructor users.
Use the "Which test?" feature to guide you to the correct statistical test --Just answer the questions about your data!

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

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!

Not an interface for RStudio
Just a warning for anyone who is as foolish as I am to think this would be a convenient rstudio interface. This just provides a web server, but uses the browser to access.
I have no idea how good this is as instructional material.
2013-11-03
Very Helpful App!
I am new to R, which appears to be a powerful yet confusing beast to master, and I have found this app to be a big help. The videos are short and to the point, and very good - they have helped me a lot to get up and running. I would welcome more of them. The reference material is also very good, and will be useful for those times when you can't remember exactly how to get R to do what you want. Responsive developer, as well. All in all a very nice app.

Committed support
I bought this app mostly to run rstudio on my mobile so I've only given the instructionals a cursory look but they look like the'd be pretty helpful. The app gets high ratings because support is scary fast & effective.
2013-09-10
Excellent Resource
And the support staff is quick to respond!

Portable analytics
It is amazing to run statistics tool in the ipad. Though more things are need to be updated, It is awesome.

Amazing app for all levels of users
There are hardly any R app in the store, but at least there is this one. It has wonderful overviews of concepts and very clear examples. Thank you for you continued work on what is already such a great app!
2013-05-10
Excellent tool
This app is am excellent reference for anyone wanting to learn R. The reference information is easy to understand and very comprehensive for a beginner to intermediate user. The ability to run R on my iPad was also a huge draw.
2013-01-24
Great for quick reference
If starting out to learn r this app is great for having a quick reference to increase user ability in r.

Great app for learning R
I'm new to the R language so I picked up this app for my iPad3. I find it very useful. The basics are well covered and the videos help show the concepts. The app comes with an interface to connect to an online version of R Studio so you can test what you learn righ inside R, very handy. The developers are helpful and responsive. I highly recommend this app if you want to learn R

Love this app
The app comes handy when you do not know where to start. Sometimes I go to google or any written instructions on how to use R, but only R-instructor gives you the most direct answer to your questions. Totally worth it!
2012-12-11
A bargain for a reference book!
This app is truly a bargain as a reference book. Plus, the navigational structure of an app makes it so much easier to find the information.
2012-10-04
Easy to use for beginners
Great app for beginners and intermediate R users!
2012-09-02
Looking good!
Really handy reference for those times that you don't want to go searching through the mountains of textbooks/instruction manuals that detail the minutiae of the R language. Also a nice stats refresher, which is never a bad thing.

1.02 still has ads
Says removed ads but there are still ads.
2012-07-02
Good reference
I'm learning to use R and find R Instructor to be a good reference. Good descriptions of functions, stats, and code to use. Good list of additional references, and videos are also helpful. Also, the ads have been removed (thanks).
2012-07-02
Very helpful
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.

Crashes
It crashes every time I open it. Never had this problem before but perhaps it's my phone? Likely not.
2012-06-13
Wow. Bad.
Three bucks and it still has ads.
Incomplete.
I want a refund.
