Subject: [Rd] describe function in package Hmisc and function format.dates
	in chron (PR#13087)
Message-ID: <20080929152503.E0461282EFC2@mail.pubhealth.ku.dk>

Full_Name: Kem Phillips
Version: 2.7.1 (2008-06-23)
OS: Windows Xp professional
Submission from: (NULL) (98.221.200.108)


The Hmisc function   describe   fails, giving the error message:

   Error in formatDateTime(dd, atx, !timeUsed) : 
     could not find function "format.dates"

Loading the chron package, where function  dates  apparently resides, does not
fix the problem.   Note also that loading  chron  gives a warning.  Earlier
versions of  chron  from the archive failed to load properly.  Please see the
entire session below, with the error message at the bottom.

Thanks.
