Hello, I have been using the "cophenetic" function for objects of class "dendrogram" and I have realised that it gives different results when it is used with objects of class "hclust". For instance, running the first example in the help file of the "cophenetic" function, d1 <- dist(USArrests) hc <- hclust(d1, "ave") d2 <-

Note that cophenetic.default (which works on the output of hclust(dist(X))) uses the row names of X as labels. as.dendrogram.hclust does not retain those row names so cophenetic.dendrogram cannot use them (so it orders them based on the topology of the dendrogram).

I think the results differ only in the order of the labels. The following function puts the labels in a standard order and then the results are the same: canonicalize.dist <- function (distObject) { o <- order(labels(distObject)) as.matrix(distObject)[o, o, drop = FALSE] } identical(canonicalize.dist(d2), canonicalize.dist(d3)) [1] TRUE Bill Dunlap TIBCO Software

Hi, XEN has a console that works in text mode ("xm console", e.g. via SSH). However with a German keyboard I''m having trouble to get out of the console again. Usually I login to Dom0 from another terminal, and then kill the xenconsole process. However I''d wish there was an easier way to get out. Maybe add a configurable escape key like for SSH?

Thanks Philon, I did read the extra bullets, as indicated in my email below. But your "When the user quits and thus closes his mailbox/connection" is more clear than "after the client is already disconnected", since the latter is really anytime, rather than at the time they quit. I can guess that the bulletin about LMTP similarly means at the end of each time LMTP delivers

Hi Folks, I thought I''d heard several months back that Xen compatibility patches were going to be rolled into the mainstream linux kernel source trees, so that in future Xen would be just another architecture one could select under make config -- not requiring a special, patched kernel. But this doesn''t seem to be the case yet. Did I misunderstand what the plans were, or is it

Here''s a topic I have not seen discussed yet: Is it possible to set it up so that traffic from any one IP or network is rate-limited? I don''t mean making a rule for a specific IP. I mean having a router/fw that will not let any one IP use up more than a specified amount of bandwidth, or be allowed to issue more than X packets per second. An example might be that you
