Introduction to R

The world is increasingly data-driven. R is the avant garde of data science. You learn some of the most modern techniques in data science and will be able to create stunning graphs with ease, develop automatic reports and get insights from your data.

The main purpose of this training is to allow the trainee to be able to independently work with R.

This is a heavily hands-on training featuring topics like:

•        grammar of graphics,
•        grammar of data manipulation
•        Rmarkdown for reports generation.

Target audience:
The course is targeted to people who are ready to move past Excel in their data analysis. The course does not assume any previous knowledge of programming/scripting. The course does not have any prerequisites.

R is used widely in the data science world and this means pretty much every sector by now – be it IT, fintech, medcine or government sector.

• It will help you to automate data-driven reports.
• It helps you to easily understand your data by visualizing it and communicate the results using publication-ready graphs.
• It helps you to apply the most modern data analytics/machine learning concepts on your data.
