Dear R users, I'm interested in measuring the stability of a heirarchical clustering, of the overall clustering and finding sub clusters (from cutting the heirarchical clustering at different levels) which demonstrate stability. I saw some postings on the R help from a while back about bootstrapping for clustering (using sample and generating a consesus tree with a web...

Hello, I'm modeling a watershed, and have a file linking individual tributaries - the name of each tributary and the water body into which it flows (which can be a tributary of another water body). I want to use this to build a tree data structure (a root, and then child nodes, linked to further child nodes, etc.). Is there a package that builds and traverses such data structures? Thanks,

Dear useRs,Is there a command or package in R to do heirarchical clustering by "modified ward method"??regardseliza [[alternative HTML version deleted]]

...y the limits which are imposed by NAT. In particular the constraints impose by the embargo on double NATing have an impact for a project I am working on. Has anyone ever seen anything which I would conceptually describe as a reverse NAT proxy? What I want to be able to do is to be able to create a heirarchical tier of networks each one of which communicates to the network above by using a modification of NAT enjoying the capability of identifying a subnet number and client. Does ayone know enough about this subject to point me in the right direction (which may be - forget about it there is no way it c...

I'd like to get a measure of goodness of fit for a heirarchical clustering result from hclust. Something that would indicate the extent to which the dendrogram accurately represents the original dissimilarity matrix. Is there an easy way to do this? Or, does anyone have code for computing distances between nodes given an hclust structure? So far, my searche...

Dear R-Help, I am working on a paper in an R course for large file support in R using scan(), relational databases, and XML. I have never used SQL or heirarchical document formats such as XML (except where it occurs without user interaction), and knowledge in RDBs and XML is lacking in my program. I have tried finding a working example for the novices-novice on the topic, read many postings, the r-data I/O manual several times, and descriptions of packages R...

Hi If I have a HTB class with 128kbit, and I want to put "N" users in that class ( in order to share bandwidth fairly ) , which is better for me ? esfq (hash dst) or wrr ? I would attach esfq or wrr to HTB parent class. Also I''ve readed on Jim script that over WRR put a RED qdisc, but I don''t understand it. bests andres

Hello R and BUGS users, I am writing a heirarchical model in R to send to BUGS via R2WinBUGS and I am finding it difficult to get the model to run. I seem to be having two problems. 1) I can't seem to send variables classed as factors (Month), is there a way do this? 2) Checking the Log in WinBUGS I can see that the model is Syntactically cor...

Hi Sir I am very new user of R for the research project on multilevel logistic regression. There is confusion about bugs() function in R and BUGS software. Is there any relation between these two? Is there any comprehensive package for Multilevel Logistic modelling in R? Please guide in this regard. Thank You RAZA --------------------------------- Boardwalk for

...eferring to a conjoint analysis scenario using R from the paper referred below: Agricultural Information Research 17(2),2008,86-94 available online at www.jstage.jst.go.jp/ This paper describes the data modelling of a conjoint study design based on conditional logit procedure. I understand that Heirarchical Bayes is asymptotically equivalent to Conditionallogit. However it would be of interest if somebody is willing to share the script to fit this data using HB in R (I understand that "bayesm" package supports HB , but I am not able to figure out exactly how to model this example data an...

My samba environment is very simple, stable and useful. I'm still running samba 2.0.x as a workgroup and having been handling heirarchal group access for years via symlinks from $HOME and Unix group perms. This machine has always been just a file server. I've been adding scsi drives as space requirements have grown. Now I have good need (due to the addition of a Win2K terminal server)

A few days ago, I initiated a conversation with Jonathan Walther to seek his advice on how he might tag a CD that I ogg'ed. Out of this discussion, we decided to make a couple of changes to the proposed standard. 1) A new LABELNO tag was added to the list. This would contain the record label's catalogue number. Generally available on the face of the CD. Probably more useful than

This is in reference to David Schmitt''s writeup [1] I like that writeup a lot; I just had a few comments/clarifications: * Namespaces: For now, we just use a flat namespace for modules, i.e. you can''t have modules within modules, and you always know that in a fully qualified name ''foo::bar::baz'' that ''foo'' is the module name and

Dear R-Users, I am currently looking for a way to test the equality of two correlations that are related in a very special way. Let me describe the situation with an example. - There are 100 respondents, and there are 2 points in time, t=1 and t=2. - For each of the respondents and at each of the time points, I have information on 10 X-variables and on 10 Y-variables. - Based on this

Hello, I'm trying to use AIC to choose between 2 models with positive, continuous response variables and different error distributions (specifically a Gamma GLM with log link and a normal linear model for log(y)). I understand that in some cases it may not be possible (or necessary) to discriminate between these two distributions. However, for the normal linear model I noticed a discrepancy

Dear all, I am facing a peculiar situation: on my smb.conf log level = 5, and on my windows machine I log on as a local administrator to add remote desktop users that are in fact domain users. When my worgroup = SOMETHING, everything works fine. When I change my worgroup to: workgroup = example.com, and try to add a new remote desktop user, and set as an object name example.com\user and try

In the course of this argument, keep in mind that I think Rails is making excellent progress in the development of documentation and community. I am only trying to develop discussion of where we need to go next. A consistent theme we are seeing on this list, I believe, is frustration caused by the lack of second-tier documentation. So far we have... -- the various tutorials which are
