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.
I have been following the Apple Guide for their new language swift, but I don't understand why the bar on the right is only showing "Hello, playground" and not "Hello, world". Can someone explain why the println isn't being printed on the right? // Playground - noun: a place where people can play import Cocoa var str = "Hello, playground" println("Hello, world");
