The R Console

The R Console

The R console is an interactive prompt where you type expressions and see results immediately, useful for quick exploration before writing a full script. Every complete expression you enter is evaluated and its value printed automatically at the console (though not inside a script). Scripts, by contrast, need explicit print() or cat() calls to show output.

Note: At the interactive console, just typing a variable's name prints its value -- but inside a script you must call print() explicitly.

Example: The R Console

x <- 42
print(x)

y <- x * 2
print(y)
