How do you clear the R console in OS X (or Ubuntu)

Question

Possible Duplicate:
Function to Clear the Console in R

In bash, its like this:

$ clear

And I believe it's CTL-L in the Windows version of R. But how do you clear the R console in Unix-type R Consoles? Do you need to write a special function and what would that look like?

Solution 1

Command+Option+L in R for Mac OS X

Ctrl+L in RStudio for Mac OS X

Solution 2

Since you ask for Ubuntu as well, it's simply Ctrl-L from a standard gnome-terminal.

Solution 3

I discovered that you call also type unix commands with the system() function.

system('clear')

Solution 4

For what it's worth, my console to R is provided by ESS on whichever platform I use -- and as that is within Emacs, it is always Ctrl-l (or C-l in the common shorthand for Emacs).

Solution 5

Create this function:

cls <- function() cat(rep("\n",100))

Then call it:

cls()

Compatible with Windows, Linux and Mac.

Here's a handy tip for finding any menu command in OS X: cmd-shift-/ to bring up the Help menu, type "clear", see where the relevant menu items are.

insert 100 newlines == clear? false

There is a much better way to do this. Rather than put 100 new lines, which is not really a clear, you can also print out the code for cntl-L.

if you wanna get fancy: clear <- function() { cat(rep("\n", Sys.getenv("LINES"))); }. But, yeah, while not a true "clear-screen," it does clear the screen and add a useful bit of space between code segments.
