Hi, I just had a very quick look at the StatDataML proposal --- nice work! At the risk of showing my ignorance, I want to mention my first impressions. My first impression is that defining datasets in terms of arrays and list is a bit too high a level. What about simpler vectors, scalars? (I know that R/S don't have scalars, but other systems/applications do.) Can we think of a core

Hi, we have a first draft of R functions reading/writing data to XML files including a rather general DTD ... which borrows heavily from the data types of a certain programming language :-) The basic idea is to create an XML standard for data exchange, together with import/export functions for as many applications as possible. We here will need R, Matlab & Octave for our research program,

Hello! I use R-version 1.0.0 To get the 0.95 quantile of the hypergeometric distribution with the parameters m=45000,n=5000 and k=600 I use the R-command > qhyper(0.95,45000,5000,600). The value obtained is 600. However, the true value is 552. The latter can be obtained for example by calling the corresponding distribution function with the R commands > x<-540:580 >

Hello, I am trying to import data from Matlab.. when i looked up R documentation, it says, package "e1071" have command (read.octave) to import data from octave. but when I tried to install package by using: install.packages("e1071"); I got the following message: ( BTW, my platform is linux version 2.4.18-3 my gcc is 2.96). * Installing *source* package 'e1071' ...

Hi, I was wondering if Statdataml is currently the preferred way to represent statistical data in XML in R. And also if the Statdataml api provides ways to load the XML as a HTTP GET? If so can you give me an easy example of this. Thanks. Cheers, Bryan Rasmussen

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

Good day: Let's say that I have a data frame in S-Plus 2000 (Win98 version). I want to use the same data frame with R on another computer. Questions: 1) Can R read S-Plus data frames? Can S-Plus 2000 read R data frames? 2) How can i move the data frame between the two systems? Do I need to use dump()? Thank you.

Hi, sorry if this is OT here. I'm trying to compile StatDataML[1] to import Matlab data into R. The R part works fine but compiling the Matlab part exits with this error message (following the INSTALL instructions: autoconf -> ./configure -> make): ,----[ patrick at trurl:~/src/statdatml/StatDataML/MatOct> make ] | make[1]: Entering directory

Hi, I was wondering if there is a standard for R function description in XML (or any plain text) format. Rd files are the closest thing I found, but they do not describe the argument (or return value) types. The purpose would be to write a program to automate the creation of C# wrapper around any R function, but without the argument type Rd descriptions are useless. Any clues... thank you

Where I work a lot of people end up using Excel spreadsheets for storing data. This has limitations and maybe some less than obvious problems. I'd like to recommend a uniform way for storing and archiving data collected in the department. Most of the data could be stored in simple csv type files but it would be nice to have something that stores more information about the variables and units.

Hi, currently the "label" and "edgetext" attributes of a dendrogram are coerced to character before they are added to a plot with `text'. Is there a specific reason to do so (expect for the determination of the size of the character string to be plotted)? Otherwise one could plot the attributes directly via diff dendrogram.R /usr/src/R/src/library/stats/R/dendrogram.R

Hi, is anybody out there who knows APL and would help me to translate 52 lines of APL code into propper R? best, Torsten

Hi, a friend of mine came across this R> x <- 1:5 R> cbind(x,x) x x [1,] 1 1 [2,] 2 2 [3,] 3 3 [4,] 4 4 [5,] 5 5 R> rbind(x,x) [,1] [,2] [,3] [,4] [,5] x 1 2 3 4 5 x 1 2 3 4 5 x is a vector and therefore has no dim-attribute. Obviously cbind treats x as a col-vector but rbind treats x as a row-vector, that is: two functions have a different

Hi, in last nights alpha version, `var' is broken: R> var(rnorm(100)) Error in var(rnorm(100)) : 3 arguments passed to "cov" which requires 4. which I suspect is due to recent changes to `cov'.

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
