You can get the coordinates of a point-pattern object with the $x and $y components. You can write to a file with R's 'write.table' function. So make the $x and $y components into a matrix, and use write.table. Here I'll use some write.table options to make a fairly clean file, coordinates separated by commas, with no row names, and nothing stuck in quote marks: write.table(file="ppxy.csv",cbind(pp$x,pp$y),sep=",",row.names=FALSE,col.names=c('x','y'),quote=FALSE) > Also, it seems that the generated graph is different on each > invocation.

See the help for 'set.seed' - type 'help(set.seed)' Baz ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
