similar to: silhouette plot colors from trimkmeans solution

I'm fairly new to the silhouette functionality in the cluster package, so apologize if I'm asking something naive. If I run the 'agnes(ruspini)' example from the silhouette section of the cluster package vignette, and assign colours to clusters, two clusters have what appear to be incorrect colours in the silhouette plot. library(cluster) data(ruspini) ar<- agnes(ruspini)

Dear R users, I am mailing you about the graphical output of silhouette (cluster package) From the example of silhouette in help(silhouette): > ar <- agnes(ruspini) > si3 <- silhouette(cutree(ar, k = 5), # k = 4 gave the same as pam() above + daisy(ruspini)) > plot(si3, nmax = 80, cex.names = 0.5) from which one may conclude that group 1 is composed by

I was trying to produced bagged importance estimates of attributes in earth using the caret package with the following commands:   fit2 <- bagEarth(loyalty ~ ., data=model1, B = 10)   bagImpGCV <- varImp(fit2,value="gcv") My bootstrap estimates are produced however the second command "varImp" produces the following error:    Error in UseMethod("varImp") : no

Hi everyone, I suspect this is an easy task however I've not been able to accomplish it. I'd like to create an mtext title which has certain words bold, the rest not bold. So far I've been able to create one which is all bold, one which is all not bold and one which has bold and not bold superimposed on one another. Any suggestion would be appreciated. Many thanks, Joe Retzer # Not

Hello, In cluster analysis with cluster, how does one colour the silhouette plots ? For example in using pam. There seems to be some problem there. Everything else can be coloured. Thanks, A. Mani Member, Cal. Math. Soc

Hi! >library(cluster) In this lib a function called silhoutte.default is defined than on the R prompt it type >silhouette.default Error: Object "silhouette.default" not found R1.9.0 The same error are at R1.8.1 And I knew that a function silhoutte.default are present. But the same piece of code works in R1.6.2 ??? Eryk Dipl. bio-chem. Eryk Witold Wolski @

Dear all, I am trying (without much success) to use the fuction 'silhouette'. Would anyone encountered that before (or would know where I am wrong ?) Please find below the R ouput. Thanks in advance, L. > s <- silhouette(ct, as.dist(metric)) Error in "[<-"(*tmp*, iC, "sil_width", value = s.i) : number of items to replace is not a multiple of replacement

Hi, I am using code below to get a plot that will show me on the X axis the number of clusters and on the Y axis the cluster average widths. However I am getting this error: Error in summary(silhouette(cutree(d, x), dist(iris[, -5])))$si.summary : $ operator is invalid for atomic vectors the code I am using is: avgs<-sapply(1:20,function(x) summary(silhouette(cutree(d,x),

Dear All, Is there any existing code for plotting silhouette for kmeans clustering results? Many thanks! Linda [[alternative HTML version deleted]]

Hi list, When I was using 'silhouette' from the 'cluster' package to calculate clustering performances, R crashed. I traced the problem to the fact that my clustering labels only have 2's and 3's. when I replaced them with 1's and 2's, the problem was solved. Is the function purposely written in this way so when I have clustering labels, "2" and

I'm using R 2.7 on an Intel MAC. When I produce a pdf graph, I save the output window from the menu to a pdf file. This gives a very nice quality graph. However when I include the graph in a LaTeX document (actually beamer presentation) using \includegraphics I get a graphic with a very light framebox around the outside. Note, I'm not using a fbox command in LaTeX. Not sure if this is

Hello everybody: I have just started using R, specifically the clustering packages. Despite the vastness of the functionality of the system, I have found it very flexible and intuitive. It has been great fun to experiment with it. Nevertheless, I am under tight time constraints to complete a cluster analysis of some data and need to come up with a "quick" solution for the following

I don't seem to be able to label the x, y or z axis when creating a 3d chart using rgl.surface. I'd like to have them parallel to the axis line and move with the graph when rotated. Can this be done? Many thanks, J. Retzer [[alternative HTML version deleted]]

Hi dear all It's the first time for me to install a developmental version of R, I came across following errors, my system is DISTRIB_ID=Ubuntu DISTRIB_RELEASE=10.04 DISTRIB_CODENAME=lucid DISTRIB_DESCRIPTION="Ubuntu 10.04.1 LTS" I downloaded the dev version of R in cran R source, and downloaded the recommended packages by using wget as described in R manual, and run

Hi Friends, I'm trying to model the consumer decisions (Click-Through Rate and Conversion) in Search Engine Advertising using a hierarchical Bayesian binary logit. The input data is the weekly CTRs and Avg. Position for each search keyword. CTR is modeled as (for each keyword i and week j): Pij = exp(C + Bi x Positionij + A1 x Lengthi + A2 x Brandi + A3 x ProductSpecifici) / [1 + exp(C +

Sorry for the long message. I'm doing my best to try to explain myself. I have fitted a spline to my data, I have fitted a spline, filled in the missing data by replicating the spline coefficients associated to the last node. I obtained a number of dendograms by different combination of distance and link-method by calling DIST and AGNES. The agglomerative coefficient is very high (~ 0.99) for

I tried using colours in silhouette plots by specifying a vector of colours instead of the default "gray" for the col parameter. No bars are drawn, though the rest of the plot works as it did with the grey bars. On investigating cluster:::plot.silhouette, I came across this part: if (do.col.sort && (lc <- length(col)) > 1) { if (lc == k) col <-

Dear List How do you change the colour settings for the banner/silhouette plot? I am trying to produce a black and white plot of publication quality. Is there a way to set black and white plots as the default for R graphics? Any help greatly appreciated. Graham Leask Economics & Strategy Group Aston University [[alternative HTML version deleted]]
