Hello All: 


      What do you think of adding a function "RSiteSeach" to the package 
of that name, masking the "RSiteSearch" function in "utils", trapping 
any call RSiteSearch('searchstring', 'function') to the current 
RSiteSearch.function and passing all others to "utils:::RSiteSearch"?  
This was suggested by a referee to a manuscript on this new capability 
submitted to "R Journal".  The current version of this manuscript is 
available via "system.file('doc', 'RSiteSearch.pdf', 
package='RSiteSearch')" if you have the "RSiteSearch" package installed. 


      Thanks,
      Best Wishes,
      Spencer
