Tab Width Resetting

shwan · April 22, 2019, 2:10pm

I have my tab width set to 4. However, RStudio appears to keep resetting the tab width to 2 spaces, although the setting itself remains at 4. The only way to fix it temporarily is to change the tab width to something else, like 6, click OK, then change it back to 4 again. However, the next time I open RStudio the tab width is back to 2. This is driving me nuts. This started happening with RStudio 1.2.

I do remember changing the tab width to 2 spaces a long time ago, but then changing it back to 4. Not sure if there's some config file somewhere that's still referring to that?

My version of RStudio: Version 1.2.1335, Build 1379 (f1ac3452)

Hmm, this might be the same bug reported here:

bug

### System details RStudio Edition : Desktop RStudio Version : 1.2.1…303 OS Version : Windows 7 64-bit R Version : 3.5.2 ### Describe the problem in detail RStudio Preview does not load indentation settings from projects correctly. ### Steps to reproduce the problem 1. Uninstall RStudio. Use a program like Revo Uninstaller to ensure that all of the user files are deleted. 2. Install RStudio Preview 1.2.1303 (this issue was also present in earlier 1.2.x Preview releases). 3. Run RStudio and close any open projects. Note that indentation is set to 4 spaces in global options. - 4 spaces is how it was set for me, at least. I can't remember the default setting, but if it wasn't 4 spaces, then RStudio has the added issue of not uninstalling itself cleanly. 4. Open a new R script (while no project is open) and note that indentation to 4 spaces is working correctly. 5. Open an existing project and one of the script files in that project (I used .Rmd). 6. Confirm that all of the lines in the project are correctly indented to 4 spaces. 7. Try to type a pipeline, like `iris %>% [RETURN] plot()`. It will only indent to 2 spaces. 8. Go to the project settings and change the indentation to something else (like 6 spaces). 9. Indentation will now work to 6 spaces. 10. Change project indentation back to 4 spaces. 11. Indentation will now work to 4 spaces. ### Describe the behavior you expected Indentation should be loaded correctly from a project.

The tab width is saved within a user-preference file located at:

%LOCALAPPDATA%\RStudio-Desktop\monitored\user-settings\user-settings

If RStudio is unable to read / write that file for some reason, then it will default back to using 2 spaces for the tab width. Could that be what's happening in your case?

It might be worth trying to reset your RStudio's state: https://support.rstudio.com/hc/en-us/articles/200534577-Resetting-RStudio-Desktop-s-State
