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 web server from your phone or tablet (Internet connection required) 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. **

To A little disappointing report today from Geoff Boucher of the LA Times ' Hero Complex download R Instructor free android app . Despite earlier acknowledgments otherwise apparently Samuel Jackson might not be back SHIELD agent Nick Fury in the upcoming Marvel films. I saw Jon Favreau at the Scream Awards and we had a conversation he said. I hope that everything works for you, because we are writing stuff for you. Then all of a sudden last to my to my agent and manager and things do not really working so well, Jackson said. What the hell happened since then? it always comes down to money. If you see it that way, obviously Marvel economic crisis is that they are going to need a lot of money to be drag pull a huge crossover movie Sun While I do that it expected a big hit, which is totally worth it to be in the end, it's a problem they need to address before they go into production. And that may mean cutting Jackson's side character from the movies. I know that Nick Fury is definitely not a side character, considering he is the leader of the Avengers team, but he does not lead his own movie, and I'm sure that Marvel does not want to pay for it a lead actor content to all the others.
