The e1071-group is developping a data exchange package based on XML, called StatDataML. Both read and write functionality is available for R/S and MATLAB/Octave. Now here is a snapshot from the "StatDataML for MATLAB/Octave"-package. It should work fine, but the installation procedure needs some improvement yet. I think the following will nevertheless make it run: 1. Get libxml 2.x

I used it in predict.svm(), and the terms-object contained in the svm model just happens to have no response for the ``one-class classification'' if svm was called e.g. by: m <- svm(~a+b). Because of the second line in delete.response() if

Friedrich, Thank you for your prompt response. Unfortunately, none of the CRAN mirrors seem to be working for me. I'm not really sure what's going on since I was able to download R about a year ago, but I recently got a new computer and needed to download it again. I'll see if my support staff here at the National Institutes of Health have any suggestions. Thanks again, Eric

Hello I've got a question about list indexing. If anyone can help or point in the direction of some documentation, that'd be great. I've checked the Introduction to R and R language definition. Say you have a list of vectors: >

Dear R user, I'm wondering if anyone was succesful in compiling R under hpux 10.20 I couldn't compile verion 1.2.1 or 1.3. I asked this question two weeks ago, but nobody replyed. Looks that not many people are using hpux machines.

Hallo, I have a question concerning SVM regression in R. I intend to use SVMs for feature selection (and knowledge discovery). For this purpose I will need to extract the weights that are associated with my features. I understand from a previous thread on SVM classification, that predictive models can be derived from SVs, coefficiants and rhos, but it is unclear for me how to transfer this

Hello list, I want to apply svm from library e1071, and I want to supply class weights. I do not really understand the help entry (and there is no example) class.weights: a named vector of weights for the different classes, used for asymetric class sizes. Not all factor levels have to be supplied (default weight: 1). All components have to be named. I have two

Hello! We are new in using R. We use the SVM module from the library ''e1071'' for training. Problem formulation: a classification has been performed using SVM module (linear kernel). Later, a new data set (test set) comparable to the training data shall be scaled in the same way as the training set (using the same scaling parameter set, but without using the SVM again

I have a dataset which I want to model using a Poisson distribution, with a given parameter. I would like to know what is the proper way to do a ''goodness of fit'' test using R. I know the steps I''d take if I were to do it ''manually'': grouping the numbers into classes, calculating the expected frequencies using ''ppois'', then

Hi Guys, I've again been surprised when something like > m <- matrix("", nrow=3,ncol=3) > index_i <- c(2,1,3) > index_j <- c(1,3,2) > vals <- c("a","b","c") > m[ index_i, index_j ] <- vals > m gives block-wise application of the assignment: [,1] [,2] [,3] [1,] "b" "b" "b" [2,]

We have a lot of diskless Linux clients which are booting via PXELINUX or ETHERBOOT. The problem is that they are on for 24 hours and APM PowerSave mode works for ETHERBOOT only. But in the future we want to use PXELINUX only, which seems to have no features for APM or ACPI PowerSave included. Would it be possible to integrate such features in PXELINUX or is there a way to boot a special image

With hist it is easy to create multiple graphs on a page but with the trellis histogram, I am finding it a bit more awkward. It seems that I have to use print(graph1, split=c(1,1,1,2), more=T) to achieve the desired result. Does anyone have code they are willing to share which

Hi, We have been running R ver 1.4.1 on a redhat linux (7.1)cluster without problem for quit some time. Now, some user wanted me to install version 1.6.1, and it compiled fine, but it crashes with "segmentation fault" when you run it. I used gcc296 (default) for compiling, Should I change compiler or is there some other thing I could do to avoid this problem. Regards Per-Anders
