# Introduction to R with Time Series Analysis

intror

## Duration

21 hours (usually 3 days including breaks)

## Overview

R is an open-source free programming language for statistical computing, data analysis, and graphics. R is used by a growing number of managers and data analysts inside corporations and academia. R has a wide variety of packages for data mining.
