[R] name of the variable that will contain the result of a function

[Benilton Carvalho]

Hi everyone,

say I have a function called 'foo', which takes the argument arg1.

Is there any mechanism that I can use to "learn" about the variable  
where foo(arg1) is going to be stored?

For example:

x <- foo(arg1)

so, inside foo() I'd like to be able to get the string "x".

if,

foo(arg1)

was used insted, I'd like to get NA.

thank you very much,

b
