Introduction to R Programming

Statistical computing is employed within a diverse range of industries. In recent years, an open source project, R, has emerged as the preeminent statistical computing platform. With its unsurpassed library of freely available packages, R is capable of addressing almost every statistical inference problem.

In this course, you will learn the most commonly-used (roughly 100) functions and operators from the R Base Package, which serves as the fundamental tools for accessing data from multiple sources, manipulating different types of R objects, performing character manipulation, and generating reports.  Furthermore, you will also learn how to write your own functions by using different types of control structures.

Topics include:

  • R objects: Vectors, matrices, arrays, lists, and data frame
  • Subsetting objects
  • Data manipulations
  • Data aggregation
  • Writing user-defined functions
  • Character manipulations

Practical experience:

Most components for succeeding in this course are practice, practice, and practice! Students are required to complete multiple sets of practice problem sets and quizzes on a weekly basis, plus two main assignments for writing user-defined functions.

Prerequisites: Knowledge of basic programming or Introduction to Programming is recommended.

Software: R, a free software environment for statistical computing and graphics, is used for this course.

Textbook: Course notes are available to download for free for registered students.

Course typically offered: Online during each academic quarter.

Next Steps: Upon completion, consider additional Data Science coursework for continued learning.
