K-means recluster data with given cluster centers Dear R user, I have several large data sets. Over time additional new data sets will be created. I want to cluster all the data in a similar/ identical way with the k-means algorithm. With the first data set I will find my cluster centers and save the cluster cent...

hello, I'm running Ubuntu Breezy with the OCFS2 modules in the standard kernel. I installed ocfs2console and ocfs2-tools I've formatted a partition with ocfs2. But I can't add any node or mount the device(with the ocfs2console). because I get a "Unable to access cluster service" I can't find the cause nor the solution to this. root@lenaeja:~# /etc/init.d/o2cb status Module "sctp": Loaded Module "configfs": Loaded Filesystem "configfs": Mounted Module "ocfs2_nodemanager": Loaded Module "ocfs2_dlm": Loaded...

Dear R user, I am a biochemist/bioinformatician, at the moment working on protein clusterings by conformation similarity. I only started seriously working with R about a couple of months ago. I have been able so far to read my way through tutorials and set-up my hierarchical clusterings. My problem is that I cannot find a way to obtain information on the rooting of specific nodes, i.e....

Are there R packages that allow for dynamic clustering, i.e. where the number of clusters are not predefined? I have a list of numbers that falls in either 2 or just 1 cluster. Here an example of one that should be clustered into two clusters: two <- c(1,2,3,2,3,1,2,3,400,300,400) and here one that only contains one cluster and would therefore...

Hi, I am using fanny and I have estrange results. I am wondering if someone out there can help me understand why this happens. First of all in most of my tries, it gives me a result in which each object has equal membership in all clusters. I have read that that means "the clustering is entirely fuzzy". Looking at the graphics it is really difficult to understand how objects with so different scores for the variables have the same membership for all the clusters. I also find estrange the fact that if I set K=3 (three clus...

Hi, I have a 2 nodes ocfs2 cluster running UEK 2.6.32-100.0.19.el5, ocfs2console-1.6.3-2.el5, ocfs2-tools-1.6.3-2.el5. My problem is that all the time when i try to run /etc/init.d/o2cb stop it fails with this error: Stopping O2CB cluster CLUSTER: Failed Unable to stop cluster as heartbeat region still active There is no...

Hi all, I am running a series of experiments where after manipulating my data I run several clustering algorithms (agnes, diana and a clustering method of my own) on the data. I wanted to determine which clustering method did the best job, so therefore I had defined my own quality measure using two criteria: compactness of the data within the clusters themselves and the amount of seperation b...

Hello, I had a question regarding clustering using the agnes() function from the 'cluster' package. I was wondering if anyone knew how I can identify cluster points after running the agnes function. For example, I created a dataset with points randomly scattered around (0,0), (0,1) and (1,0). After clustering, the dendrogram sho...

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi everyone, another problem I did not find a solution for... I ran "o2cb configure" and configured a cluster named "ocfs2". Lazy me, I did not invent a new name. Now this cluster must be renamed to avoid confusion, the name has to change to "sapcluster". I changed /etc/ocfs2/cluster.conf to the new name and ran "o2cb configure" again, but to no avail: - ---snip--- # rco2cb...

Dear list, I just tried to use the function cluster.stat in the package fpc. I just have a couple of questions about the syntax: cluster.stats(d,clustering,alt.clustering=NULL, silhouette=TRUE,G2=FALSE,G3=FALSE) 1) the distance object (d) is an object obtained by the function dist() on my own original matrix? 2) clustering is the clusters vector a...

I want to make a cluster with two simple (INTEL SATA) pcs using CentOS, my question is? Is there something easiest than Linux RedHat Cluster Manager to make a cluster using CentOS with just two pcs? Regards, Israel

Dear R users, I'd like to ask u whether you know how to sort out the following: I'm trying to reproduce a dataset of clusters, and for that I need to build up a cluster index (inside a function) using the command "replicate" as follows: dataset<- function( clusters=100, cluster.size=50, outcome.mean=list(mean=3, sd=1), outcome.var=list(mean=0, sd=1), treat=1, unbal = FALSE){ if(clusters%%2!=0) stop("...

Hi all! I'm new to R and don't know many about it. Because it is free, I managed to learn it a little bit.
