change git username and update source in R

At one point you feel your username could be better, but the implication of changing the username will be devastating. I tried this once. I thought it is fine.  could be only worked with version control Project in R
1. change the username on the Github,
2. rename the folder source (repository folder) in local drive
3. create new version control project with new URL from Github web
4. R will automatically clone the file structure from Github web
