Introduction to R Programming

In this R training course, students learn to program by diving into the R language and then use their new-found skills to solve practical data science problems. They'll learn how to load data, assemble and disassemble data objects, navigate R's environment system, write functions, and use all of R's programming tools.

What people say about our training

Excellent virtual class supported by enthused instructor and relevant lab sessions.
Glenn Crouch

An impressive class environment to introduce or clarify SQL Queries. Having an instructor-led program allows for a myriad of questions to be answered immediately, to clarify the documentation, and to provide examples real-time for us.
Dennis Tetreault

I went in with no Visual Basic experience and I now feel like I am able to perform basic functions using Visual Basic. The teacher was great and I look forward to taking more Webucator courses in the future.
