After I Open the program, it says "'\O' is an unrecognized escape in character string (:1:12)
[Workspace loaded from ~/.RData]". The error also occurs when I try to compile a report. This happens after I change Region format To Chinese in Windows. I switch the setting back, but the the problem persist. Any idea how to fix it? thanks
~/.RData is most likely the last workspace saved when you exited an RStudio session. Presuming that you do not need to resume where you left off, you could try deleting the file and see if that fixes the problem. If not, you could try resetting RStudio's state.
Okay. I find the Source of problem. It is related to Rprofile. There's a line in it which contains '\O' . After delete it, R functions well
