In the present world, when we are getting drowned in the heap of data, it is very important to use tools & techniques to get meaningful knowledge & information from data. This highlights the need of data science in the present world. Companies across the globe are using various tools of data science to get key insights from their business data and in-turn improving their bottom line. That’s why the role of a data scientist is getting important with day by day. According to industry experts data scientist is considered at the sexiest job of 21st century.
R is a powerful and widely used open source software and programming environment for data analysis. R is one of the top 5 open source programming language in data science. R has been ranked 9 amongst all programming languages. R popularity is increasing rapidly day by day. R has become de-facto standard language among data analysts across the globe. R is used by some of industry giants such as facebook, google, twitter, New York times for various data analysis activities such as data pre-processing, prediction, forecasting, data visualization etc. According to Dice Salary Survey , 2014 , R is among the highest paid IT skill in US.
I have recently authored a course on “R Programming Fundmentals” available on Pluralsight. This course will provide everything you need to know to get started with the R framework, and contains a number of demos to provide hands-on practice in order to become an efficient and productive R programmer. By the end of this course, you will also learn to play with data and to extract key information using various R functions and constructs.
Course contents ( Total content length : 06h 58m) :
This first module will provide you all information you need to know to get going with R framework. We will discuss the reasons of using R framework for data analysis projects.We will also go through the process of installing R and RStudio IDE on the local machine. By the end of this module, you will be familiar with R framework and things you can accomplish using R programming.
This module will discuss ways to get help, if you come across any confusion or problem, while learning R programming. By the end of this module , you will know where and how to get help if you run across cross any issue in your R endeavors.
Module 3: R : Variables & Operators
This module will cover some of the fundamental blocks of R programming such as variables, environments and operators. This module will also talk about vectorized operations and its benefits.
