I was working on a base project consisting of multiple folders and files.
I'm not sure what happened but all the contents of the project somehow got deleted. The only thing that remains is an empty Project. Even the file project.Rproj is deleted, so that the project became unusable.
It's my fault for not using version control I guess, but this seems like an important issue nonetheless.
It's unlikely I deleted 4 folders (data/, rmd/, src/, doc/) along with all the project files by accident. I did not call any terminal command either.
What could have caused this?
I can share more information with the RStudio team if needed but I can't publicize the project contents on the internet (not that it's possible now anyway).
