Your code contains

onion.R:"Re.default" <- get("Re",pos=NULL,mode="function")
onion.R:"Im.default" <- get("Im",pos=NULL,mode="function")

and has been giving deprecated warnings for a while (and ?get does not say 
NULL is allowable).  The relevant NEWS item is

    o	Use of NULL as an environment is now an error.


You need pos="package:base" there.
