R help - Sep 2009 - Function "Varcov" in Design (Ver. 2.2-0) package

Hi,

I'm running into an error message for the "anova"-function I never
got
before with the Design (Version 2.2-0) package.

There seems to be a missing function "Varcov", please check my  
function calls (it's in german but I think you get the error):

 > library(Design)			## attaching Design package and dependent packages
Lade n?tiges Paket: Hmisc		## loading dependent packages
Lade n?tiges Paket: survival
Lade n?tiges Paket: splines

Attache Paket: 'Hmisc'


	The following object(s) are masked from package:survival :

	 untangle.specials


	The following object(s) are masked from package:base :

	 format.pval,
	 round.POSIXt,
	 trunc.POSIXt,
	 units

Design library by Frank E Harrell Jr

Type library(help='Design'), ?Overview, or ?Design.Overview')
to see overall documentation.


Attache Paket: 'Design'


	The following object(s) are masked from package:Hmisc :

	 strgraphwrap


	The following object(s) are masked from package:survival :

	 Surv

 > corr.lrm = lrm(CORRECTNESS ~ condition * type, data = data2)
 > anova(corr.lrm)		## everything seemed to work fine, so run anova on  
the fitted model.
Fehler in anova.Design(corr.lrm) : konnte Funktion "Varcov" nicht
finden

Error message translated: Error in anova.Design(<model>) : couldn't  
find function "Varcov".

Any ideas?! Thanks in advance!

This is an error in the most recent Hmisc update. The authors promised 
to deliver another update that fixes this issue.

Please read r-help messages from 2 days ago that contain a simple
