Get name of function in R

Question

I have a function f:

f=function(){}

and a variable

var=f

I would like to know how to get the name of the fun

Answer 1

var=f assignes function(){} to var. It only knows that it is a function and 'forgets' about variable name. This code:

f <- function(){}
var <- f

has the same effect as this:

var <- function(){}
