	  I'm not certain what you are asking.  Do you want to fit a time 
series model using Bayesian Model Averaging (BMA), or do you want to 
predictions with confidence intervals from a BMA fit or both?  For any 
of these, I suggest you start with the posting guide! 
"www.R-project.org/posting-guide.html" and with "RSiteSearch" in 
particular.  I just got 31 hits from 'RSiteSearch("Baysian model 
averaging")', which included discussions of the BMA and ensembleBMA 
packages as well as an article on "BMA:  An R package for Bayesian Model 
Averaging" by Raferty, Painter and Volinsky, 3 of the 4 authors of the 
BMA package.

	  I couldn't find a function for a BMA time series fit.  If I wanted 
that, I'd probably start by asking the maintainers for "BMA" and 
"ensembleBMA" (cc'ed on this reply) and by reading the code for the 
nearest things I could find.  I'd make local copies of one or more 
functions and try to walk through the code line by line until I thought 
I understood it well enough to modify it to do what I wanted.  With 
luck, someone may reply to this email with hints or even code that might 
make that task easier.

	  hope this helps,

p.s.  If I had understood your question better, I might have been able 
to supply more useful suggestions.
