R help - Nov 2011 - HoltWinters in R 2.14.0

Hey All,

First time on these forums.  Thanks in advance.  

Soooo...  I have a process that was functioning well before the 2.14 update. 
Now the HoltWinters function is throwing an error whereby I get the
following: 

Error in HoltWinters(sales.ts) : optimization failure

I've been looking around to determine why this happens (see if I can test
the data beforehand) but I haven't come across anything.  

Any help appreciated!

I believe there were some changes to Holt-Winters, specifically in re
optimization that probably lead to your problem, but you'll have to
provide more details. See the NEWS file for citations about the
change. If you put example code/data others may be able to help you --
I haven't updated yet so I can't be of much help.

Michael
