Function to clear the console in R and RStudio

Question

I am wondering if there is a function to clear the console in R and  in particular  RStudio I am looking for a function that I can type into the console  and not a keyboard shortcut   Someone has already provided such a function in this StackExchange post from 2010  Unfortunately  this depends on the RCom package and will not run on Mac OS X
