# Data Science with R Training in Marathahalli

“R” is a highly extensible and open source language used for statistical computing and analysis. Some of the commonly used statistical techniques using “R” are Linear and nonlinear modeling, time series analysis, clustering. “R” can be combined with any of the platforms like UNIX, Windows, MacOS, Linux and FreeBSD. It allows a data analyst to perform the data reporting, data manipulation and representation easily and effectively by using graphical in-built facilities available in “R”. Overall “R” is a well-developed programming language which includes loops, conditions, user defined recursive functions and lot more.
