The error occurred because the CTP3 install had some manual steps to configure R Services & those are separate from SQL Setup. In this case, the user accounts created by CTP3 for the default instance already exists and the new install of RC3 will fail. As a result, you have to repeat the manual uninstall steps for R Services too.
To resolve the error, you can follow the steps from the link below (section: Uninstalling previous versions of R components):
