Quit and restart a clean R session from within R?

Is there a way I can make an alias, within R, that will execute q() and then restart a clean R session?

And yes, I am too lazy to type q() and then the letter R :)

If you're in RStudio: command/ctrl + shift + F10

You can also use

.rs.restartR()

Depending on how you start R try placing one of these lines into your .Rprofile file:

makeActiveBinding("refresh", function() { shell("Rgui"); q("no") }, .GlobalEnv)

makeActiveBinding("refresh", function() { system("R"); q("no") }, .GlobalEnv)

Then entering this into the R console:

refresh

will shut down the current session and start up a new one.
