A warm welcome to the Data Visualization with R course by Uplatz.


Data Visualization refers to quantitative analysis that allows us to explore data and communicate our findings. In data science, analyzing your data is only half the battle - communicating your data and results to share knowledge and facilitate decision making is also essential. Data visualization is a powerful tool that can allow people across all ranges of statistical know-how to understand complex patterns and findings.

Not only the R programming language was specifically designed for statistical computing, it was also developed with a focus on graphics. As well as the standard plotting functions available in base R, additional functionality is also available through add-on packages of code. The ggplot2 package was developed by Hadley Wickham as part of the tidyverse (a collection of packages designed with data science in mind) and is considered one of the best tools for plotting graphs. It combines high levels of customization with clean and visually pleasing graphics, often with minimal effort put in on the part of the programmer. Thus ggplot2 is basically a set of packages that aim to make data management, analysis and visualization more user-friendly. It contains a wide range of options to customize plots and can be used for all types of data.


Uplatz provides this in-depth training on Data Visualization using R. This Data Visualization with R course helps you to effectively create figures based on your quantitative data. If you want to understand your data better and add impact to your publications, Data Visualization in R is the right course for you. Understand the art of visual communication and practical implementation of data visualization. This is done using the R statistical programming environment with your own data.
