R help - Jul 2010 - stl function

Hi all, 

I'm working on decomposition and comparison of several time series. I'm
interested in extracting the trend components for each time series using the
stl function and overlaying them on one another.  

I'm not sure how to plot the trend function alone and to do the overlay
using some kind of loop. If anyone has any insight that would be great!

thanks, 

Katie

stl(...)$time.series

is a "ts" series containing seasonal/trend/remainder. Thus, the trend
can
be extracted via

stl(...)$time.series[, "trend"]

See ?stl for more details.
