Using R in Displayr Video Series

This article contains a list of videos guiding you through various examples of working with R in Displayr. There have been some changes in Displayr since these videos were released. These changes are noted in the requirements below. However, the examples and explanations remain relevant. The videos are ordered from introductory to advanced. If you are short on time, you can also browse through specific examples in the Displayr document/QPack listed alongside each video. All the content presented in these videos is also available as individual Displayr Help articles.

Requirements

A Displayr document with data - or you can follow along with the videos using a copy of the example code in your Displayr account accessible through the links below.
- If you're using our sister software Q, you can download the QPack version to follow along.
A few changes to keep in mind:
- The Displayr interface changed and the Insert menu used heavily in the videos is now gone.
  - R Outputs - previously created by Insert > R Output are now called Calculations and can be accessed by selecting Calculation > Custom Code.
  - R Variables - previously created by Insert > R > Numeric variable (or Text variable) are now created by hovering in the Data Sources tree and clicking + > Custom Code > R - Numeric (or R - Text)
- Since the release of the videos, we have introduced point-and-click functionality when editing R code. This means you can add code by clicking on outputs or variables in order to reference them automatically instead of having to copy and paste in the Name and Index of each output - see How to Use Point and Click Inside R Code.
