 Reviews
R is a popular choice of tool for data science professionals, offering a large variety of libraries pertaining to each and every task in data science. With practical examples based on various realworld domains and usecases where R and its libraries can be used, this course will be your companion for implementing those tasks using the free, open source libraries provided by R.
This comprehensive 2in1 course equips you with all the essential skills required to perform data science tasks with ease using practical, realworld scenarios. It follows a stepbystep approach to teach you the fundamental concepts of R programming and usage of its libraries such as, setup, working with complex data, performing data analysis, data mining, and data visualization with ggplot2, Plotly, Leaflet, GoogleVis, Motion Chart, and Joy of Stats.
This training program includes 2 complete courses, carefully chosen to give you the most comprehensive training possible.
The first course, Speaking ‘R’ – The Language of Data Science, begins with an introduction to R and setting up the development platform. You will then be introduced commands in R, which are very useful and not as common in traditional languages since manipulating data is more important in R. You will also look at an example of Titanic dataset, which is the kind of thing you’ll come across in R, a multidimensional collection of variables of different types. Using the tools that we cover we can form a picture, a story behind the data. Next, you will learn how to clean up the data. Finally, you will learn some basic statistics with R using special features for data visualization.
In the second course, HeavyLifting Using R Libraries, you will begin by looking at highperformance computing in the classic, computationally intensive scenario: finding prime numbers. You will then learn how to use R, before moving on to using C++, which is far faster. Next, you will use the power of parallel, though that varies from problem to problem since some are more suitable for parallelization. Finally, you will look at some powerful options available in R where you don’t just produce a static result but instead respond to user selections.
By the end of this course, you will be able to confidently use the R programming language for performing data mining, data analysis, and data visualization.
Meet Your Expert(s):
We have the best work of the following esteemed author(s) to ensure that your learning journey is smooth:

Dr. Samik Sen is a Theoretical Physicist and loves hard problems to think about. After his Phd, which was about developing computational methods to solve problems for which no solutions existed, he began thinking about how to tackle the maths problem while lecturing. He developed algorithms to generate problem sets and solutions, and learned how to create video lessons. He has developed a large Facebook community teaching school maths around Ireland, with associated elearning products and YouTube channel. Samik is currently fascinated by machine and deep Learning.He has developed a machine learning system which is performing better than he can himself which was the hope.

8Putting It All Together
In this video, we are now ready to write programs.
Write our program
Check manually for a few numbers to see that seems to be working
Test it for larger size against known answers to confirm that we're right

9Core R Types
In this video, we will look at R data types which are new.
Look at Vectors, Matrices, data frames, and lists
Learn how to initialize and index them to select elements
Look at mtcars, one of the included data sets with R

10Some Useful Operations
In this video, we will introduce some key commands to study data.
Understand the use of thestructure and summary commands
Understand the use of the head and tail commands with few examples
Learn how the View command lets us see the data in a spreadsheet style

11More Useful Operations
In this video, we willintroduce various commands to help us pick out elements in which we are interested in.
Understand how the sequence and repeat commands generate a list of numbers, so we can pick out those entries
Learn how the subset and which commands let us pick out elements with certain properties

12Titanic
In this video, we will investigate the Titanic dataset to see what it says.
See that this is not simple one dimensional information
Find out how to index through the data and get a handle on it
Produce plots which tell us a story
