Ok, in the above it was important that there's no *existing* object x.e 

Note that the idea about  fix() is that you only have to write


But your problem remains :

    > fix(newerf)
    Waiting for Emacs...Done	--- I have  options(editor = "emacsclient")
    > newerf
    function ()
    ## newer
    <environment: 0x40862004>
    > environment(newerf)
    <environment: 0x40862004>
    > ls(env=environment(newerf))
    [1] "subx" "x"   

I.e. it got the environment of the function fix -- I think this is clearly
a bug  CC'ed to  R-bugs

    Erin> Why is this, please?  (It's not a bug....I just wondered).

it *is* a bug, I think

same for Unix

    Erin> Thanks!
thank you for the report!
