-lowess- doesn't allow weights. Apart from programming
this yourself, I guess your only option is to -expand- 
beforehand. Assuming that community size is an 
integer, then this in some cases might lead to problems
with dataset size, especially if the communities are e.g. 
ants or other social insects.
