[R] Why don't the comments appear in the function?

Different version of R perhaps?   Or is there something in my environment
or "preferences" that is different?

Here's what I get with your example.

>  f <- function(x){
+     ## a comment
+     2
+  }
> g <- list(a =2, fun =f)
> g
$a
[1] 2

$fun
function (x)
{
    2
}

> g[[2]]
function(x){
    ## a comment
    2
 }
> g[1]
$a
[1] 2
