Hello. I'm trying to use the functions pandit and treebase. They are in the package apTreeshape. Once I've loaded the package, R responses: - no function pandit/treebase. Somebody knows why or what is the reason? Thanks, Arnau. ------------------------------------------------------------ Arnau Mir Torres Edifici A. Turmeda Campus UIB Ctra.

Hello. I'd like to compute the associate vector of distances between leaves in a binary non-rooted tree. The definition of a distance between two leaves in a binary non-rooted tree is the number of edges in the path joining the two leaves. I've tried the ape package but I'm unable to find this vector. For example, using rtree(5,rooted=F) I've obtained the following tree: $edge

Hello. Consider the following matrix: mp <- matrix(c(0,1/4,1/4,3/4,0,1/4,1/4,3/4,1/2),3,3,byrow=T) > mp [,1] [,2] [,3] [1,] 0.00 0.25 0.25 [2,] 0.75 0.00 0.25 [3,] 0.25 0.75 0.50 The eigenvectors of the previous matrix are 1, 0.25 and 0.25 and it is not a diagonalizable matrix. When you try to find the eigenvalues and eigenvectors with R, R responses: > eigen(mp) $values [1]

Hello. I need to know how can R compute AIC when I study a regression model? For example, if I use these data: growth tannin 1 12 0 2 10 1 3 8 2 4 11 3 5 6 4 6 7 5 7 2 6 8 3 7 9 3 8 and I do model <- lm (growth ~ tannin) AIC(model) R responses: 38.75990 I know the following formula to compute AIC: AIC=

Hello. Somebody knows if there exists some R package that it is capable of doing the same of the software ExpertFit (see http://www.averill-law.com/ExpertFit-distribution-fitting-software.htm)?

Hello. I need that Sweave writes R output to a file. To do it, I put the following into the foo.Rnw file: \documentclass{article} \usepackage{Sweave} \begin{document} ... <<echo=F>>= x <- rnorm(100) y <- rnorm(100) sink("foo.txt") summary(lm(y~x)) sink() @ ... \end{document} When I run: R CMD Sweave foo.Rnw R responses: Warning message: In sink() : no sink

Hello. I want to create a list of vectors but each component of the list has a different length. For example: Example=list() Example=list(Example,c(1,2,3)) Example=list(Example,c(11,12,13,14,15)) If I want the first component of the Example list, I have to write: Example[[1]][[2]]. R responses 1 2 3 The second component: Example[[2]]: 11 12 13 14 15 If I iterate the previous example,

Hello. I have a lot of files that contain tables of data in a directory. I want to do the following in R but I don't know how: for i in 1 to the number of files { table[i]=read.table(file="file i") } The dimension of each table is different. All of these are tables of two dimensions. My first problem is to put all the file names in a table. Next, how I can load them using the

Hello. Somebody knows how to compute generalized hypergeometric series in R? (see http://functions.wolfram.com/HypergeometricFunctions/HypergeometricPFQ/02/ to understand what I mean) Thanks in advance, Arnau.

Hello. I have the following distance matrix between 8 points: [1,] 0.000000 3.162278 7.280110 8.544004 7.071068 9.899495 6.403124 8.062258 [2,] 3.162278 0.000000 5.000000 6.403124 4.472136 8.944272 6.082763 8.062258 [3,] 7.280110 5.000000 0.000000 1.414214 1.000000 5.000000 4.242641 5.830952 [4,] 8.544004 6.403124 1.414214 0.000000 2.236068 4.123106 4.472136 5.656854 [5,] 7.071068 4.472136

Hi all, my name is Arnau Bria and I''m a sys admin in a center where we must deal with hundred hosts. We''re currently working with quattor, but it''s too complex for our purposes, so I''m looking for new admin tool. I''ve been playing with CFengine for few days (2 or 3) and I''ve seen some limitations that makes me thing that CFE is not our

Hello. Is it possible to choose the distance in the kmeans algorithm? I have m vectors of n components and I want to cluster them using kmeans algorithm but I want to use the Mahalanobis distance or another distance. How can I do it in R? If I use kmeans, I have no option to choose the distance. Thanks in advance, Arnau.

Hello. In the file list.txt, I have the name of n files in data frame format. I want to make an image for each file and save the images in pdf format. To do this, I do the following: llista = scan(file="list.txt",what=list(nom="")) for (file.name in llista[[1]]){ aux=read.table(file=file.name) aux=as.matrix(aux) pdf() image(aux)

Hello Conrad, I'm trying to seek the way you told but I'm facing a problem. ogg_page_packets returns 164 and following code returns 189. Shouldn't it be the same, what does that means ? int res; while (true) { res = ogg_stream_packetout(&os, &op); if (res == 1) nPackets++; if (res == -1)
