R Programming Training Overview

Accelebrate's Introduction to R Programming training course teaches attendees how to use R programming to explore data from a variety of sources by building inferential models and generating charts, graphs, and other data representations

Location and Pricing

Most Accelebrate courses are delivered as private, customized, on-site training at our clients' locations worldwide for groups of 3 or more attendees and are custom tailored to their specific needs. Please visit our client list to see organizations for whom we have delivered private in-house training. These courses can also be delivered as live, private online classes for groups that are geographically dispersed or wish to save on the instructor's or students' travel expenses. To receive a customized proposal and price quote for private training at your site or online, please contact us.

In addition, some courses are available as live, online classes for individuals. See a schedule of online courses.

R Programming Training Prerequisites

Students should have knowledge of basic statistics (t-test, chi-square-test, regression) and know the difference between descriptive and inferential statistics. No programming experience is needed.

Hands-on/Lecture Ratio

This R Programming training class is 60% hands-on, 40% lecture, with the longest lecture segments lasting for 15 minutes. Students "learn by doing," with immediate opportunities to apply the material they learn to real-world problems.

R Programming Training Materials

All R Programming training students receive a copy of Addison-Wesley's R for Everyone and related courseware.

Software Needed on Each Student PC

  • R 3.0 or later with console
  • IDE or text editor of your choice (RStudio recommended)
