Data Visualization in R
About the training
Visualization of data allows one to present it in a graphic form. Such a form enables to understand data, find patterns and dependencies which are important in making decisions. Anyone, who tried to convince the investor or help the manager in making a decision by showing a huge data sheet or a complicated report knows that it only leads to frustration and misunderstanding. Presenting data in graphic form makes understanding of complicated data and conclusions easier.
Currently, R is one of the most popular tools used in data analysis. Due to the number of useful functions and packages as well as its rapid development people became interested in using R. What makes it even more attracting is the fact that you can use it for free. It is a perfect, easy to use tool for data visualization.
Who is this training for?
The training is aimed at people who are willing to learn creating readable graphs in R. We always try to match the level of our training with the level of students knowledge but to make it even more efficient participants should know the basics of using R.
We recommend the training to:
Analysts, consultants, managers and statisticians.
The participants of our training work with R in a number of different branches(finance, production, medicine, etc.). We always try to put great emphasis on such elements of R, which are the most needed in everyday work.
