Setting up RStudio to use the Viewer Panel (feat. MacOS sudo)

Build Your Own Free Website Part 5 - Quarto Basics Have you ever done a render in a post and the browser pops up and you can't see the render screen? It's a little annoying when the browser keeps popping up every time you render.

But what if you want to see the rendering results directly in RStudio itself? Shouldn't there be a way to do that? In this post, we'll answer that question. You can use the Viewer to see the rendering results without a browser popup.

Setting up the RStudio Viewer Panel

Windows operating systemIf you're using RStudio from RStudio, you should be able to get this set up very easily. From the menu, select the Tool > Global Option > R Markdown > Basic in the 'Show output preivew in : ' drop-down button. The default is Window, but you can change this to Viewer Panein the list. Wow, that was easy, wasn't it?!

Setting up MacOS RStudio

In this setup, the issue is with MacOS users. If you follow the process above, you'll see the rstudio-prefs.json permission issuesand you're faced with an error warning. What do we do about it? Let's take a look at the workaround.

This error occurs when the macOS user does not have the permissions associated with setting RStudio options. To resolve this issue, use the Grant administrator privilegesTo do this, first open a terminal window, and then run the following commands one by one in sequence to fix the issue

sudo -s
cd ~/.config/rstudio
chown username rstudio-prefs.json

sudo -sand hit enter, switch to administrator mode, enter your MacOS login password, navigate to the rstudio-related directory, and grant permissions to the settings-related file (rstudio-prefs.json). When you're done exit command to exit administrator mode. Finally, exit and re-launch RStudio.

Viewer Panel Rendering Screen

After doing the above, if you try to render in RStudio, you will see the rendered screen in the Viewer Panel, as shown in the following figure.

Tips for rendering

Here are some additional rendering tips. Normally, you would edit your source code and render it to see the changes. However, as shown in the image belowRender on Save' option, when you save your quoto document, the viewer will automatically render it with your changes. This is much easier to work with because you don't have to do any rendering, just save and the rendering is done automatically, so we recommend checking it.

If you are a VS Code user and not RStudio, you can use the method introduced on the official Quoto website (Click Shortcuts) to set this option. We'll write a more detailed introductory post in the future.

Organize

In this post, we'll show you how to use the RStudio Viewer Paneland we learned how to set it up so that you can check the rendering results in the Terminal, which is a bit more technical for macOS users because of the permissions issue. Finally, we learned about the option to automatically render when saving the small code, which is a bit more technical for macOS users than for Windows OS users.
