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

Buenas noches; vengo con una consulta, que no se si es fácilmente resoluble o necesito saber más para entender porqué no tengo que hacer lo que me propongo. Tengo una matriz de distancias y unos clusters según metodo "ward" que me los da una web construida hace ya unos años. Supongo que fue publicada en el 2012, por lo que estará construida en el 11, 10 o antes). Esta web me devuelve unas agrupaciones (el gráfico) o me permite a mí bajar la matriz de distancias. Bajé la matriz de distancias y pretendí replicar...

We appear to have some phantom DNS records on both our domain controllers. We can see the records using "dig", but not with samba-tool. We can't remove the records either. (v-ward and v-fief are the DCs, Hawaii and Alaska are old DCs which were demoted without errors, I'm trying to clean up some DNS records which don't seem to have been cleaned). All machines are 4.2.10-Debian Can anybody advise how I can fix this? Ideally in this case there would only be two recor...

Hi folks, I am trying to do a clustering and generate a long dendrogram in R on Linux server: ========= data<-read.table(file="mean_ratio.txt.noheader",row.names=1,sep="\t",quote="\"") hc<-hclust(dist(data),"ward") png(file="mean_ratio.txt.noheader.ward.png",bg="white",pointsize=8,width=32767,height=1536) plot(hc,hang=-1) dev.off() ========= I found that 32767 is the largest width I can go. I tried 32768 and the graphics becomes all black. I need to go higher since even with 3276...

...s, 2=no). I did two similar cluster analyses, one on SPSS 18.0 and one on R 2.9.2. The objective is to have the means for each variable per retained cluster. 1) the R analysis ran as followed: > call data > dist=dist(data,method="euclidean") > cluster=hclust(dist,method="ward") > cluster Call: hclust(d = dist, method = "ward") Cluster method : ward Distance : euclidean Number of objects: 277 > plot(cluster) > rect.hclust(cluster, k=4, border="red") > x=rect.hclust(cluster, k=4, border="red") > sapply(x, func...

Hi. Does anyone have samba 2.2.2 on Solaris 8 working with winbindd? I have samba 2.2.2 installed and configured --with-winbind and have the winbindd daemon running but the following does not work: 1. "getent passwd" Solaris command on returns local users (no Domain users) 2. winbindd authentication to the PDC is not occurring. 3. local users cannot change password since I modified the

...or characters. My question is - is there a better or more efficient way of doing this, maybe with apply or something. My first thought was apply set to operate over all columns, but was unsure of the indexing and selecting columns to be deleted. Thanks, Ben W.

...ama on line al que no tengo acceso para ver cómo hace los cálculos. Yo tengo los datos, y el programa también me da la matriz de distancias. Quiero, además, tener los clusters (no el dibujo, si no el elemento: elemento <- hclus(dis.df)) Pero el elemento que yo genero con hclus(dis.df, methd = c(ward.D, ward.D2) genera agrupamientos que no coinciden con los que me devuelve en el plot. No sé si lo que yo quiero hacer es 'replicar' o solamente 'repetir'. Que es como lo diría en casa. Tengo entendido que en algún momento no muy lejano se cambió algo en la manera de calcular los cl...

Dear R-Help-Team, I would like to cluster my data using the ward-method. In several papers I read (e.g. Bahrenberg) that it is neccesary to use the "squared euclidean distance" with the ward-method. Unfortunatelly I cannot find this term in r as a method for measuring the distance. Does anybody have an idea? Thanks in advance, Carolin [[alternative...

Dear R community, I am trying to understand how the ward linkage works from a quantitative point of view. To test it I have devised a simple 3-members set: G = c(0,2,10) The distances between all couples are: d(0,2) = 2 d(0,10) = 10 d(2,10) = 8 The smallest distance corresponds to merging 0 and 2. The corresponding ESS a...

Hello, I want to use pearson's correlation as distance between observations and then use any centroid based linkage distance (ex. Ward's distance) When linkage distances are formed as the Lance-Williams recursive formulation, they just require the initial distance between observations. See here: http://en.wikipedia.org/wiki/Ward%27s_method It is said that you have to use euclidean distance between the initial observations. H...

Hi, I'm currently using EMA package to make clustering and heatmaps. The online doc concerning the package gives the following example code: data(marty) c<-clustering(marty, metric="pearson", method="ward") clustering.plot(c, title="Hierarchical Clustering\nPearson-Ward") which is working perfectly, However, when I'm changing the method to method="kcentroids", on the exact same example, I got the following error: Error in DIS$DIS : $ operator is invalid for atomic vect...

Hello Users: I'm using R version 2.0.1, and having problems with RODBC. Everything works fine when I use Rgui, but when I try to use Rterm and issue the commands library(RODBC) con <- odbcConnect("MySQL", "test") I get the following error: Error in sqlQuery(con, str) : first argument is not an open RODBC channel In addition: Warning messages:

...ter(0) attr(,"na.action") [1] 1 attr(,"class") [1] "omit" I want to get rid of these elements/positions in the list, since a function is supposed to sample the list for elements (each element is a collection of about 20 numbers each).

...this is found to be the case for the training data. I have tried using the maximum within class distance for the training data to set the h variable in cutree for the clustered new data. This appears to work fine for "average" and "complete" clustering methods but not for the Ward clustering method as the distance axis of the dendrogram does not directly relate to the distances between observations. Can anyone advise on how to optimise the h value of cutree when using the Ward clustering method or is there a better approach to this type of classification problem? Thanks Mi...
