Subject: [Rd] Retrieving function name
Message-ID: <op.tiq898r6ffxks9@norisk>

Hi,

Does anyone know how I can retrieve a function name, for example

If I have a function f as follows:

f <- function( myfunc ) {
	print( name_of(myfunc) );
}

I want to know what I should have as "name_of" such that I could call this  
with :
	f( median )
and it would print "median"

or f( my_function_name ) and it would print "m_function_name".

So far all I can get is the function definition that myfunc points to.

I thought the structure command might do it but this also just gives back  
the function definition and not the original name.

Any suggestions?

Tom
