[R] Echoing commands (not using source())

[Henrik Bengtsson]

Is there a way of echoing (similar to Matlab "echo on") commands that are
being executed? I know how to do this for script files by using source(...,
echo=TRUE), but I would like to be able to use this within *any* function. I
am also not looking for the debug() function. Here is what I would like to
do:

myFunction <- function() {
  echo(TRUE);
  x <- 3;
  cat("x = ", x, "\n");
  echo(FALSE);
}

Output:
>myFunction()
x <- 3;
cat("x = ", x, "\n");
x = 3
>


Thanks
