[R] .Rhistory in R.app

[Rob Goedman]

Maria,

Try changing the name of .Rhistory in the Startup preferences to something like .Rosxhistory. Press enter to make sure the change is accepted and try again.
The problem is that R itself overwrites the file .Rhistory if it is told to save the workspace.
