I tried to Setup an odbc connection from R to my PostgreSQL database located on a server (package RODBC). When trying to connect the connection failed because I entered a wrong Username in the DSN connection defined in odbc.ini.
So I changed
odbc.ini and tried again but then RStudio froze. So I killed the process and tried to start the application again. Unfortunately now RStudio didn't start at all anymore (the app in the launcher blinks but does not open the UI). I already uninstalled the application with
sudo apt-get purge rstudio
and reinstalled it again. I updated and upgraded all packages...but still the same error. Also trying to start the program from terminal typing rstudio does not give any result. So any idea how to debug this and get Rstudio working again?
Edit: when i start rstudio from terminal with
it shows me the ID 7547. Still this ID doesn't appear in the processes list in the system monitor.
