R help - Nov 2009 - Akaike weight in R

I am using lm simulation in R and try to find the AICc and Akaike weight of
the model. I searched out that using package "AICcmodavg"  AICc is
easily to
get. I wonder how can I get the "Akaike weight", any function I can
use to
generate it? Thanks in advance.
