ctrl - e & l
Any funcation that is callable from my program, instead of pressing keys?
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")
On my terminal, this required the addition of cursor homing
to replicate the effects of using the OS to clear the screen.
system_cls <- function() system("clear")
vt100_cls <- function() cat("\033[2J\033[H")
