R help - Oct 2012 - HoltWinters

Hi,

I am trying to fit the HoltWinters exponential smoothing on a monthly time
series data in R. My questions are:
1. I know that the level, trend and seasonality are updated over time. So
are the output coefficients a, b and s1-s12 for a specific time t (a,b and
s12 for last observataion for example) ?

2. I am trying to work out the fitted values but I could not figure out
the h value used in HoltWinters function?

Thanks in advance
Sara B.
