The popular, open source statistical programming language “R” is widely used in both academia and industry or data analytics. According to a recent survey, R is the 15th most used programming language. We can work directly in R, but RStudio provides a more friendly programming environment. Importantly, Rstudio can be used only in conjunction with R. In this workshop, we will present in RStudio.
Both R and RStudio are free. The links below provide two short videos indicating how to download and install R and RStudio (Please install both):
The introductory workshop includs three sections.
- In the first section, we focus on the basic data types used in R. We will introduce vector, matrix, data frame and list.
- In the second section, we introduce the basic graphic skills, such as:
- how to plot different types of graphics, including scatter plots, box plots, bar charts, pie charts;
- how to add points and lines;
- how to add legends;
- how to adjust the margins;
- how to lay out multiple graphics.
- In the last section, we will work on a real case together.
At the end of the workshop, participants will:
- have a conceptual understanding of how R works,
- know how to use R as a calculator and basic data manipulation tool,
- be able to produce useful graphical and numeric summaries of data,
- understand the general steps to conduct a statistical analysis,
- be aware of the availability of relevant packages to expand R’s capabilities as needed.
