The "Introduction to R" (from Cran website) also talks about it. See pg
49 - section 10.4 (was just reading this the other day).

      In S-Plus, the function "outer" can't find "n2".  In the form

outer(1:n3,1:n3,function(x,y,n2.=n2){n2. - pmax(x,y)}), n2.=n2)


      the value of "n2" is passed to "n2." as part of the "..." 
argument.  Someone else mentioned Venables and Ripley (2000) S 
Programming (Springer).  Please see this or some other discussion of the

"..." argument. 

      hope this helps.
