Part 1: Starting with R – installation : http://msprogrammer.serviciipeweb.ro/2016/10/03/starting-with-r-as-in-sqlserver-r-server-and-vs-package/

Part 2: Starting with R – language and data http://msprogrammer.serviciipeweb.ro/2016/10/10/starting-with-r-language-and-data/

Part 3: Starting with R – basic and statistics http://msprogrammer.serviciipeweb.ro/2016/10/17/starting-with-r-basic-and-statistics/

Part 4: Making diagrams with R ( and transformation of data) : http://msprogrammer.serviciipeweb.ro/2016/10/31/making-diagrams-with-r/

Part 5:  Forecasting currency exchange with R   http://msprogrammer.serviciipeweb.ro/2016/11/06/forecasting-eurbnr-currency-exchange/

The http://tryr.codeschool.com/ also features a gentle introduction to R – if you do not know programming  .

As in other programming languages, you can store values into a variable to access it later. Type x <- 42 to store a value in x.

x <- 42

I have typed :

> x<-7

And site answers by:

`x` should be set to the number `42`. Try again!  # this is the site answer ….

> x<-42 # made by me

( and site goes to next exercise – although you can trick to strings …)

The next  best tutorial ( comprised on six parts) I have found here:

http://www.computerworld.com/article/2497164/business-intelligence/business-intelligence-beginner-s-guide-to-r-get-your-data-into-r.html

( did you know about data() command ?)

Anyway, those are the six parts

After that , if you have a Pluralsight subscription, this course is worth looking : http://www.pluralsight.com/courses/r-understanding-machine-learning  -  it gives you a short introduction to MachineLearning with R
