R help - May 2001 - about s.window in stl

Hi,

Is there anybody who could explain a little bit the use of s.window and
t.window in STL. If I decompose a series using the default values,  I get a
very irregular trends, but if I play with the options, I get less rare
trends. If anybody can explain me the concepts behind these options I will
appreciate a lot. I'm not a mathematician ;-)

Thanks in advance

Cheers,

Antonio
