3 minutes to Writing R
Write and practice your first R program with us today.
Hi there! Welcome to this Data Science Dojo video series on learning R and basic programming for data science.
R is a programming language, open source and free software environment for statistical computing and graphics. It has quickly developed
a huge community support. This language is used among statisticians and data miners for:

developing statistical software

data analysis

data visualization

data science

machine learning

statistical techniques (such as statistical tests, classification, clustering and data reduction)
Although R has a command line interface, there are several thirdparty graphical user interfaces, such as RStudio, an integrated development environment, and Jupyter, a notebook interface.
This tutorial will teach you the basics of R. It is not necessary to have any prior programming experience. This introduction to R video series will not only get you up to speed in R but also programming 101 or programming foundations.
Today you will write your first program which is a classic “hello world” print statement. You will also, create a variable name and assign or store string values  the words “hello world” to that variable  and use the print function
to print out the variable to what we just stored inside that variable.
To get started watch the video.
