Access to and Manipulation of the Body of a Function

Get or set the body of a function.

body(fun = sys.function(sys.parent()))
body(fun) <- list

`fun`	a function object or a character string naming the function to be manipulated. If not specified, the function calling `body` is used.
`list`	a list of R expressions.

body returns the body of the function specified.

The assignment form sets the body of a function to the list on the right hand side.

body(body)
f <- function(x) x^5
body(f) <- expression(5^x)
f(3) # = 125
str(body(f))
