### Description

**Learning Path overview **

Have you ever wondered how you can turn your massive datasets in to useful information for your team, organisation or business? Then R is the language you need to learn.

This learning path introduces the fundamental concepts and knowledge you need to use the programming language R, a mathematical and statistical modelling language used extensively in data analysis and Big Data.

By attending this course you will learn how to write programmes using R to create effective statistical outputs and to visualize data using R’s library.

**Intended Audience **

Aimed at all who wish to learn the R programming language.

**Prerequisites of the Course **

No prior knowledge of R is assumed

Delegates should already be familiar with basic programming concepts such as variables, scope and functions

Experience of another scripting language such as Python or Perl would be an advantage

Having an understanding of mathematical concepts will be beneficial

**Learning Objectives **

At the end of this course you will be able to understand:

- The basics of R
- How to download and install RStudio
- What makes RStudio unique
- Datasets in RStudio
- Basic operations in R
- Variables, Booleans, operations and integers in R
- Data Structures in R
- Functions in R
- Operators in R
- Conditional Statements in R
- Implicit Control Flow in R
- Plotting in R

**Agenda **

This Learning Path contains videos, PDFs, and labs for 10 courses.
