R Instructor

R Instructor


R is a free statistical, graphing and data manipulation software. Anyone who works with data can benefit from learning 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 public web server from your phone or tablet (Internet connection required -- do not expect a super computer -- this server is for experimenting with your scripts) and teaches R using plain, non-technical language and over 30 videos. 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.

** As an added bonus – If you don't know the statistical test you need, use the included "Which test?" feature! Just answer the questions about your data. **


Use R Instructor to:
-Run a server-based implementation of RStudio from your mobile device. This is a shared server, and does not appear to work with the Galaxy Note series of devices.
-Get help with R using our forum.

Learn R's fundamentals:
- R's interface
- Create objects
- Install libraries\packages
- Import and export data and plots
- Merge data frames
- Exclude redundant data between datasets
- Import dates
- Create custom functions
- Summarize data frames and matrices
- Perform calculations
- and more...

Learn how to make and customize plots:
- Box plots
- Bar plots
- Histograms
- Line charts
- Scatter plots and scatter plot matrices
- Add and customize legends
- Add custom axis labels
- Modify the size, shape and colour of point markers
- Add axis titles
- Add lines, text or points to an existing plot
- Add colour to the plot background, border lines… and just about anything else!


Learn these (and more) statistical tests:
- One-sample t-test
- Two-sample t-test
- Paired t-test
- Correlation

Plus,
- Over 30 videos
- 10 Quick Reference Guides
- The "Which test?" feature – An assistant to guide you to the appropriate statistical test

*** Note, to view the videos you must be running the Gingerbread (v2.3) or a later operating system. On Android devices running much older operating systems (generally v2.1 and older) a slightly different build of R Instructor but with the same text information may download. Very few devices now run 2.1. ***

Recent changes:
v.2.03
Fixed a bug that was causing text to overlap pictures on some newer devices.

v.2.02
Completely new build and interface
Stability enhancements and interface improvements
Improved video player
New content: qplots (from ggplot2) and more base plot customizations
Bug fixes

v.2.01.7
- Bug fixes

Heads up The description makes reference to the shared R STUDIO server not working with Galaxy Note. Tested 'ok' with Note 3 unrooted on Lollipop. Keyboard keeps switching to uppercase though which is a bit annoying. Another keyboard might help. Looks useful so far! Edit - upgraded rating from 4 to 5 : Following a couple of email exchanges with developer, he responded and fixed my issue within 24 hrs. Top notch developer, would buy again.

I thought it would have all the topics that R covers. Disappointed
