This short course provides an intensive, hands-on introduction to the R programming language to provide students with the fundamental programming skills required to start their journey to becoming a modern day data analyst.

Course Objectives

Upon successfully completing this course, students will:

  • Be up and running with R
  • Understand the different types of data R can work with
  • Understand the different structures in which R holds data
  • Be able Import data into R
  • Perform basic data wrangling activities with R
  • Compute basic descriptive statistics with R
  • Visualize their data with base R and ggplot graphics

Structure of Class Time

The two in-class sessions will consist of both lectures, live coding by the instructor and hands on programming by the students. The hands on practice will be sequential in which students will practice applying code as it is learned.

Local Usage

R is open source and you can install the latest version from cran.r-project.org. For a better experience, you may also want to install RStudio: www.rstudio.com

You should have no issue installing on personal devices (Windows, MacOSX, Linux). In order to perform a local installation on a work device, it is advised to contact your CI.
