We cannot know if you use it right, since you have not given any details on OS, R version, sn version, and particularly a reproducible example. As each R-help message tells in the footer: "PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code."
