Bug: NOTE, Objects in \usage without \alias

[munterfi]

Version: 0.9.1 
Check: Rd \usage sections 
Result: NOTE 
    Objects in \usage without \alias in documentation object ‘autocomplete-defunct’:
     ‘autocomplete’
    
    Objects in \usage without \alias in documentation object ‘set_auth-defunct’:
     ‘set_auth’
    
    Objects in \usage without \alias in documentation object ‘set_proxy-defunct’:
     ‘set_proxy’
    
    Objects in \usage without \alias in documentation object ‘traffic-defunct’:
     ‘traffic’
    
    Functions with \usage entries need to have the appropriate \alias
    entries, and all their arguments documented.
    The \usage entries must correspond to syntactically valid R code.
    See chapter ‘Writing R documentation files’ in the ‘Writing R
    Extensions’ manual.
