Hello R users It's some time I am playing with a dataset to do some cluster analysis. The data set consists of 14 columns being geographical coordinates and monthly temperatures in annual files latitutde - longitude - temperature 1 -..... - temperature 12 I have some missing values in some cases, maybe there are 8 monthly valid values at some points with four non valid. I don't want to

Hello everyone I am trying to use CLARA method for finding clusters in my spatial surface temperature data and noticed one problem. My data are in the form lat,lon,temperature. I extract lat,lon and cluster number for each point in the dataset. When I plotted a map of cluster numbers I found empty areas in the map. The point is that the number of points that were assigned a cluster number are

Hi everyone I have a question about clustering. I've managed using CLARA to get a clustering analysis of a large data set. But now I want to find which is the right number of clusters. The clara.object gives some information like the ratio between maximal and minimal dissimilarity that says (maybe if lower than 1??) if a cluster is well-separated from the other. I've also read something

hello, i'm pete ,how can i order rows of matrix by max to min value? I have a matrix of membership degrees, with 82 (i) rows and K coloumns, K are clusters. I need first and second largest elements of the i-th row. for example 1 0.66 0.04 0.01 0.30 2 0.02 0.89 0.09 0.00 3 0.06 0.92 0.01 0.01 4 0.07 0.71 0.21 0.01 5 0.10 0.85 0.04 0.01 6 0.91 0.04 0.02 0.02 7 0.00 0.01 0.98 0.00 8 0.02

Hello R-listers, I'm having trouble accessing "sub" objects ("attributes"?), e.g., "x$silinfo$avg.width" using the /get() /command; I'm using/ get()/ in a loop as illustrated in the following code: #FIRST MAKE CLUSTERS of VARYING k /for (i in 1:300){ assign(paste("x.",i,sep=""),pam(x,i)) #WORKS FINE }/ #NEXT, TAKE LOOK AT AVE.

I am using some functions from package clusterSim to evaluate the best clusters layout. Here is the features vector I am using to cluater 12 signals: > alpha.vec [1] 0.8540039 0.8558350 0.8006592 0.8066406 0.8322754 0.8991699 0.8212891 [8] 0.8815918 0.9050293 0.9174194 0.8613281 0.8425293 In the following I pasted an excerpt of my program:

Hi All, For the function "bclust"(e1071), the argument "base.method" is explained as "must be the name of a partitioning cluster function returning a list with the same components as the return value of 'kmeans'. In my understanding, there are three partitioning cluster functions in R, which are "clara, pam, fanny". Then I check each of them to

Hi, I would like to know if someone knows an extended implementation of k-means in R to find appropriate number of clusters for a given k-dimensional data. Also, I am working on clustering for forecasting, if someone is interested or has knowledge on implementational details please mail me, I would appreciate it. Regards Skanda Kallur "Cogito, ergo sum" (I think, therefore I

Hi All, These are the code that i used to plot the kmeans clustering. DataSetS01022<-rbind(matrix(rnorm(50),ncol=2), + matrix(rnorm(50),ncol=2)) > colnames(DataSetS01022) <-c("timeslot","em") > (cl <-kmeans(DataSetS01022,2)) >plot (DataSetS01022, col=cl$cluster) > points(cl$centers, col = 1:2, pch = 8, cex=2) Now, i would like to do *the same process

Hi: I'm clustering a microarray dataset with a large # of samples. I would like your opinion on the best way to automatically determine the optimal # of clusters. Currently I am using the "cluster" package, clustering with "clara", examining the average silhouette width at various numbers of clusters. I'd like opinions on whether any newer packages offer

Hi Im maintaining a samba server and Im with an unknown files inside /var/spool/samba. It seems to refer users but I don't know If I can delete something or not. files are type -rw------- 1 usuari Domain Users 0 2012-03-07 17:05 smbprn.00004993.KyICia Someone knows what is it? Thanks

Are any plans for an API that would allow ZFS commands including snapshot/rollback integrated with customer''s application? Thanks, Cherry

After ordering the table of membership degrees , i must get the difference between the first and second coloumns , between the first and second largest membership degree of object i. This for K=2,K=3,....to K.max=6. This difference is multiplyed by the Crisp silhouette index vector (si). Too it dependending on K=2,...,K.max=6; the result divided by the sum of these differences I need a final

Hello everybody! I should have an error on the LDAP entries of my ldapSAM, but I've read several times chapters 11 & 12 of the Samba HOWTO Collection and I cannot fix it. Let's explain: I've got a StandAlone fileserver (not PDC) samba-3.0.4 with ldapSAM working on a RedHat Enterprise 3.0 (linux kernel 2.4.25). The directory server version shouldn't be important, but

Hi! I've been trying to install Samba 3.0.2a + ldapSam (Stand-Alone, not PDC) on a RedHat Enterprise Edition 3.0 as a fileserver. It works fine but I still get some errors about groups and I can't find the answers in the mailing list log: Let's explain the error: When I connect with a W2k client it works fine, but then if I try to add extra permissions to a file it complains

Hi everyone As I couldn't succeed with manual installation of Rmpi I decided to start again from the beginning. I removed R and MPICH in my Ubuntu Hardy installation. Then, to avoid any dependencies problems I have installed MPICH and R from synaptic, not from sources. But now I can't install Rmpi. An error message appears when trying to install Rmpi, you can find in

Hi R-users I'm a beginner with R and statistics, so I need some help to start my data analysis. I've been reading some docs and tutorials on R and cluster analysis. I've got a large dataset (102000 points) with values of longitude, latitude and temperature and want to see if I can find groups (clusters). Following some tutorials I can look for principal components but get an error

Hi everyone I am new to R and have a question about missing values. I am trying to do a cluster analysis of monthly temperatures and my data are 14 columns with spatial coordinates (lat,lon) and 12 monthly values: /lat - lon - temp1 - //temp2 - temp3 - .... - //temp12/ If I omit missing values (my missing values are 99.00) with /mydata <- na.omit(mydata)/ every row with a
