[Rd] "note: symbols.rds is not available"

[Ben Bolker]

  I've encountered this note in checking packages with the latest
R-devel. Googling finds it only in other package checks; searching the
source tree finds in src/library/tools/R/sotools.R , but I'm not sure
what it's doing there.


'symbols.rds' shows up in the SVN log here:

r58591 | ripley | 2012-03-05 07:25:58 -0500 (Mon, 05 Mar 2012) | 1 line

treat non-symbols.rds reports on base packages differently

r58539 | ripley | 2012-03-01 04:54:39 -0500 (Thu, 01 Mar 2012) | 1 line

comment if expecting symbols.rds and not found


  Any thoughts? Is it harmless?  How would I fix the issue/suppress
the note?

  thanks
