R Code file is becoming 0 KB after saving

[PRASOONA]

Hello Team,
It will be great if anyone can help
I've been using R for my data science course and usually, I've been using R for all course activities. Now I got a weird problem all R Code files after saving are becoming 0 KB whichever I saved from the past two days.
I tried uninstalling all my R and R Studio apps and reinstalling even then the problem did not get solved.

Thanks

Hi, Try changing to R 4.1.3. That solved the problem for me. The files are not actually empty, but there is some bug with the RStudio editor. I had this error myself with R 4.2.0.

Or at least this sounds like the same error. When I tried to open any file, the Rstudio editor showed it as empty. When opening the file with a different editor, it wasn't empty.

This is a known bug with RStudio and R 4.2. We have just released a new version of RStudio that doesn't have this problem, 2022.02.3. Get it here:

Posit

Apologize for the inconvenience!

Thanks @ freudianguy,
I tried opening in a different editor on a couple of files that had the code of lines and the rest are loaded as junk characters.
Hence I downgraded the version and worked on the projects.
