Re: [R] how to clear screen in R-console?

Hi,

depends on what type of terminal you are running. For example, if you run R in a VT100 terminal, you can try

cat("The following VT100 escape sequence will clear the screen on a VT100 terminal\n")
cat("\033[2J") # <ESC>[2J == Clear Screen cat("If the screen was cleared you should only see this sentence.\n")

i.e.

vt100ClearScreen <- function(...) cat("\033[2J")

Some links:

Note, this is not guaranteed to work everywhere. To the best of my knowledge, you will not be able to do anything like this in Rgui on Windows.

Cheers

Henrik
