R help - Dec 2009 - get the enclosing function name

Hi,

Is there a way to get the enclosing function name within a function?

For example, I would like to have a function getEnclosingFunctionName().
It works like below

f = function(){
  print(getEnclosingFunctionName())

}


f()  # will print  "f"


Thanks

Jeff

Try placing this in your function:

Name <- match.call()[[1]]

Try this;

f <- function()as.character(sys.call())

Hi,

.NotYetImplemented gives an example,

function ()
stop(gettextf("'%s' is not implemented yet",
as.character(sys.call(sys.parent())[[1L]])),
    call. = FALSE)
<environment: namespace:base>

HTH,

You confused me at first with "enclosing function", but I think you
can
do what you want using something like

f <- function() {
   print(sys.call()[[1]])
}

f()
