Just a quick heads up here, that deleting the body text of a message or changing the subject line, does not alter the 'linkage' between posts. There are standards for how messages are 'threaded' and largely have to do with the e-mail headers, not the e-mail content. A couple of quick references that might be helpful: http://people.dsv.su.se/~jpalme/ietf/message-threading.html http://www.jwz.org/doc/threading.html HTH, Marc Schwartz ______________________________________________ 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 and provide commented, minimal, self-contained, reproducible code.
