I agree that
Here is one way:
foo <- function(tmp) assign( tmp, tmp , '.GlobalEnv')
> foo('ick')

[1] "ick"
Note that you must only use it with a character argument:
> foo(1)
Error in assign(tmp, tmp, ".GlobalEnv") : invalid first argument
Be warned also that assign() should be used very carefully,
What an awful idea... that would lead to incredibly hard-to-debug programs. No,
you cannot do that. What kind of problem has led you to want such a capability?
Perhaps we can suggest a simpler way to think about your problem.

Hello,
I would like to use the variable name which i assign the return value
of a function in a function. Is that possible?
e.g.
foo <- function(){
some not to me known R magic
}
myVariableName <- foo()
myVariableName
[1] "myVariableName"
Hope someone can help me.
Thanks
Florian
