[Rd] Because it's Friday. was creating environments in package's C code

[spencerg]

      I hope you will forgive a serious comment on this thread, but the 
new "sos" package makes "greping through the headers" shockingly easy.  
It returns the 'RSiteSearch( ___ , "function")' information in a 
data.frame of class "findFn" sorted to put the package with the most 
matches first.  Duncan Murdoch wrote a "???" alias for this "findFn" 
function.  Union and intersection operators are defined for 
"findFn"objects.  The "findFn2xls" function writes an Excel file with 
three sheets giving an extended package summary, the matches (including 
the URLs), and the call.  An article on this is scheduled to appear in 
the next issue of "R Journal" and is available now via vignette('sos'). 


      This "sos" package is not as good as greping Ripley's frontal 
lobe, but it makes it quite easy to do a literature search of all 
contributed R packages.
