Hello, 
I was trying to convert an object of class tess generated using the spatstat package into a shape file, just as shown in this posting: 
 https://stat.ethz.ch/pipermail/r-sig-geo/2009-January/004854.html
Then I tried coercing my object into a owin object as follows:   

owin.points<-as.owin(tess.points),  where tess.points comes from:
centroid.points<-ppp(results$cluster_X, results$cluster_Y, c(-4,4), c(-4,4))  
tess.points<-dirichlet(centroid.points)

but the owin object (owin.points) would only return the tesselation's window and lose other points.
Has anybody found a way to do the conversion?
Any suggestions are welcome,
