hello all, I would like to introduce a summary table into the pdf along with the plots (in order to archive my data into single files automatically). Similarly, It would be great to have the result of the statistical analysis (for instance anova) in the same file. Is there a way to do that? example: pdf("example.pdf") layout (matrix(1:2,1,2)) plot (groups, scores) Result <-

Hello all, may be someone can give me a hint how to solve a little problem. I'm trying to create some expressions inside a for-loop which i want to evaluate AFTER this creation loop (but loop specific). To explain my problem here comes the code: y.mat <- t(matrix(rep(84:90,8) + as.numeric(gl(8,7)),nrow=7)) # > y.mat[1:2,] # [,1] [,2] [,3] [,4] [,5] [,6] [,7] # [1,] 85 86

Dear R people, I am trying to install rimage using install.packages("rimage") but am receiving the following errors despite having FFTW installed. I would appreciate any help to get this fixed. checking fftw.h usability... no checking fftw.h presence... no checking for fftw.h... no configure: error: Sorry, can't find fftw header ERROR: configuration failed for package

Hi, I am sorry to be asking this but the wiki is down and has been for a couple of days and I need to get this working before Monday to get my live system setup. Trying to get the Snom 190's and soon to arrive 3com 3102's to use the function keys and for the life of me I can't work it out from the conversations on the archive what I am going exactly wrong here? The snom 190 with

Hi, How can I calculate and mark each group centroid in a linear discriminant analysis plot (using ggplot2)? Script: ## originate from http://r.789695.n4.nabble.com/LDA-and-confidence-ellipse-td4671308.html require(MASS) require(ggplot2) iris.lda<-lda(Species ~ Sepal.Length + Sepal.Width + Petal.Length + Petal.Width, data = iris) LD1<-predict(iris.lda)$x[,1]

Does anyone know how hclust (stats) calculates centroid linkage if only a distance matrix can be used as the input? ...Tao

Hello, I need to calculate the centroids of some spatial polygons that I have placed into a Polygons-class object. Is the labeling point in the Polygons-class the centroid of the polygon? Thank you for your help.

Dear UseRs,i want to find centroid of clusters, which i generated by hclust. Is there a way doing that? i took mean to elements in each cluster to get centroid but i am not sure if i am right? thanks in advanceeliza [[alternative HTML version deleted]]

Dear everybody! In the function hclust, at each stage distances between clusters are recomputed by the Lance-Williams dissimilarity update formula according to the particular clustering method being used. Using "centroid" method, Lance-Williams recurrence formula works properly only for euclidean distance. How is it possible to use properly centroid method with manhattan distance ?

There seems to be a bug in hclust (package mva) for clustering methods 'median' and 'centroid'. I have written a clustering program in C and discovered that the results for 'median' differ from those of hclust in R. I used a third program, written by someone else in Pascal, and that program agrees with the output of my program. I found yet another clustering program that

Dear All, I am using a specific approach for my master thesis. In essence, a supervised reclassification is used as an intermediate step to find chemical parameters which are able to reclassify defined groups. These variables will be used in a next step where location and scale estimators of the groups are important. Traditionally linear discriminant analysis is used for reclassification which

Helo there. I am using kmeans of base package to cluster my customers. As the results of kmeans is dependent on the initial centroid, may I know: 1) how can we specify the centroid in the R function? (I don't want random starting pt) 2) how to determine the optimal (if not, a good) centroid to start with? (I am not after the fixed seed solution as it only ensure that the

Dear R community, I would be greatful if somebody could shed light on the following. I have created a set of 6 points to check how centroid agglomeration works in cluster analysis: > Y <- data.frame(x=c(-1,1,1,-1,10,12),y=c(1,1,-1,-1,0,0)) It is quite intuitive to understand that the last clusters to be joined will be {1,2,3,4} with {5,6}. Now, the centroid for the first cluster has

Given a data set with a group factor, I want to translate the numeric variables to their centroid, by subtracting out the group means (adding back the grand means). The following gives what I want, but there must be an easier way using sweep or apply or some such. iris2 <- iris[,c(1,2,5)] means <- colMeans(iris2[,1:2]) pooled <- lm(cbind(Sepal.Length, Sepal.Width) ~ Species,

Hey, all, I'm trying to construct a centroid plot using canonical values from a MANOVA. I know that from the summary.manova object you can get Eigenvalues, and the H and E matrices (from SS$Treatment and SS$Residuals), but I am at a loss to get the loadings for the canonical values, nor values for the centroid centers and radii. Is there a package that does this that I am just missing,

Hello, I got this problem: I want to mount a directory without providing a login/password [indicaf$]. I thought that "guest ok = yes" would be sufficient. But it not works.
