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
