About the training

The training deals with the most important elements of programming which are crucial in creating apps and packages in R. More and more companies and institutions notice the potential of using R as a tool for data analysis. Our training enables you to work with R freely and discover the best programming techniques. It will make you a better and more skilled employee.

The training is conducted by data science experts using Live script method. We put great emphasis on the practical applicability thus during the training we constantly work with R. Instead of using presentations, we discuss all concepts while programming in R. It makes the learning process easier and much more efficient.

Who is this training for?

We created this training to answer the needs of our customers who are interested in programming and creating software in data analysis branch. If you are a scientist or an analyst who works with R and you are willing to develop your skills and gain useful knowledge about R, you should consider our training.

Data Analysts, Consultants, Statisticians, Engineers, Data Scientists
