Summary ---

For this video, we take a look at the Positron IDE's R session features. We focus on using an R project and a single R script file. We explore different portions of the interface, including the famed interactive data viewer.

This video covers a large gambit from setting up keyboard shortcuts similar to what is available in RStudio to creating interactive plots using the {plotly} package.
