Hi all,
In follow up to my reply to Terry Therneau on r-help regarding the lack of a
check in hist.Date() for a missing 'breaks' argument, attached is a proposed
patch which includes such a check, patterned after the same check for
hist.POSIXt().
The patch is against the current svn 'trunk' version of datetime.R in package
'graphics'.
Regards,
Marc Schwartz
