Yes.
    attr(myfun,"source")<-NULL
or you  can turn off non-prettying for all new functions by setting
   options(keep.source=FALSE)

R, by default, keeps a copy of the source code for a newly created
function (though not for a function in the base package). The primary
reason is to ensure that comments stay exactly where they are put, which
is quite hard to arrange when parsing and deparsing.

BTW, this is described in the 'Writing R Extensions' manual, where we
recommend prettying up the code of packages, followed by hand-editing.
