R help - Mar 2009 - Does R support double-exponential smoothing?

I want to use double-exponential smoothing to forecast time series
datas,but I couldn't find it in the document,does R support this
method?

Hi,

ets() in Hyndman's forecast package allows you to specify which one of 
the many smoothing variants (additive/multiplicative season, damped 
trend, additive/multiplicative errors) you want.
