I have recently experienced a serious problem with Rstudio when developing a package. Whenever, I open an existing project with Rstudio where versions are controlled with Git, it takes so long for it to respond to any command. It is also impossible to type something in the console (e.g. 1+1) and obtain the result. Even quitting the Rstudio, should be done with task manager. There is no problem when I create a new project / package or when I open directly a R script.
This problem appears both when the project is saved on a dropbox or on a local repository.
To overcome this issue everytime I need to modify my code, I create a new project, and then I move toward the new repository all my current R scripts and the folder ".git".
I would appreciate if anybody could help me with this issue.
