Remove unused function

[MichaelChirico]

No other reference to this function, and it's not exported:

Thanks! I don't remember why I added this function now. It should be okay to remove it.

I'm also not sure! It was added unexported and not used anywhere at the time so it's not like it just became obsolete by accident:

I'm sure you had something truly marvelous in mind at the time, it just couldn't fit in the narrow margins of one commit 😉

Haha, from my vague memory, perhaps I was doing some hack on win-builder because win-builder lacked the very latest version of a certain package.

Details

I used this function temporarily in the Authors@R field of DESCRIPTION to update win-builder's package. Don't tell the HiddenLayer guys, otherwise they'd claim that they found another "vulnerability" of R (arbitrary code execution in DESCRIPTION). Well, seriously, I have always thought Authors@R was a bad idea, but due the lack of support for recursive data structure in DCF, perhaps the evil eval() is the only way to go.

That is indeed pretty devious 😆
