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.

This is absolutely Superb. Thank you for working us through some of the great feature of this awesome IDE. I hope it works well with Quartto.

Yes i am loving it so far, seemless experience with R and Python, i never liked working with Python in R studio, that was a mess for me tbh, Positron is a breeze. Quarto works fine too. So far i haven't encountered any issues, except that i am not able to move the panes around.๐ ๐

Thank you so much for creating this video!
-
Thanks. This was helpful. One thing I was absolutely missing is that, on Windows, ctrl-enter runs the line and sends the output to the console. Still a lot I don't understand about the functionality, but at least at this point I can use it.
-
This should be good in the future, especially for R. But they need to enable remote ssh / dev containers! On their list, but not yet there.
-
I couldn't find the "zoom" option in the plots? Is is still there in Positron or is is just in Rstudio?

Great video!! Is it possible to load GitHub Copilot in Positron?
-
This thing is just a rehash of what we already have with Code, as this software is a fork of it, and marimo and jupyter.
-
Prove me wrong but this is just vscode ๐
