Chapter 1 Welcome!

Hi, and welcome to the R Module 1 (AKA STAT 158) course at Colorado State University!

This course is the first of three 1 credit courses intended to introduce the R programming language to those with little or no programming experience.

Through these Modules (courses), we’ll explore how R can be used to do the following:

  1. Perform basic computations and logic, just like any other programming language
  2. Load, clean, analyze, and visualize data
  3. Run scripts
  4. Create reproducible reports so you can explain your work in a narrative form

In addition, you’ll also be exposed to some aspects of the broader R community, including:

  1. R as free, open source software
  2. The RStudio free software
  3. Publicly available packages which extend the capability of R
  4. Events and community groups which advocate for the use of R and the support of R users

More detail will be provided in the Course Topics laid out in the next chapter.
