R is a programming language and software environment for statistical computing and graphics supported by the R Foundation for Statistical Computing. 

The R language is widely used among statisticians and data miners for developing statistical software and data analysis  .  R is an integrated suite of software facilities for data manipulation, calculation and graphical display. It includes

•    an effective data handling and storage facility,

•    a suite of operators for calculations on arrays, in particular matrices,

•    a large, coherent, integrated collection of intermediate tools for data analysis,

•    graphical facilities for data analysis and display either on-screen or on hardcopy, and

•    a well-developed, simple and effective programming language which includes conditionals,    loops, user-defined recursive functions and input and output facilities.

RStudio is an integrated development environment for R, a programming language for statistical computing and graphics. It is available in two formats: RStudio Desktop is a regular desktop application while RStudio Server runs on a remote server and allows accessing RStudio using a web browser.

R is installed on your computer and uses your personal computer resources to process R programming language. RStudio integrates with R as an IDE (Integrated Development Environment) to provide further functionality. RStudio combines a source code editor, build automation tools and a debugger.

In this course  we will setup an R environment  and perform data analysis and visualisation.
