[R] all.equal and names?

[Spencer Graves]

Hi, Duncan: 

      Thanks much.  I think I remember reading about both "all.equal" 
and "identical" in Venables and Ripley (2002) MASS.  Unfortunately, I 
don't have MASS handy now, and I could not find it otherwise, so I asked. 

      What needs to happen to upgrade the "all.equal" documentation to 
add "identical" to the "see also"? 

      Best Wishes,
      Spencer
