Documented arguments not in \usage in documentation object ‘matlist’:

[kylebaron]

This is new with rdevel

Version: 1.0.9
Check: Rd \usage sections
Result: NOTE
    Documented arguments not in \usage in documentation object ‘matlist’:
     ‘.x’
    
    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.

This currently only shows up with r-devel and I can't install it to reproduce. I did test this on winbuilder and found that the change eliminates the NOTE.
