Dear useRs, it is our great pleasure to announce the new package "relations" to appear on all CRAN-mirrors soon. This package provides data structures and methods for creating and manipulating relations, relation ensembles, sets, and tuples. The feature list includes: * creation of relations by domain and graph/characteristic function/incidences, * extraction of characteristic

Dear useRs, Version 0.2 of package "relations" appeared on CRAN and is currently propagating to the mirrors. In addition to some bug fixes, the new release includes: o an introductory vignette showing the main features; o new SD fitters for the C ("complete") and A ("antisymmetric") families of relations; o a fitter for Copeland's method; o

Dear all As part of an ongoing study on the ecomorphology of ant communities, I have obtained a matrix with 156 row (species) and 20 columns (several measurements of body shape) for 4 localities. For each community, I calculated a matrix of Euclidean distances between all pairs of species. From this matrix, I extracted two measures of community structure: i) I identified the distance from a

Hi, I would like to calculate the RELATIVE euclidean distance. Is there a function in R which does it ? (I calculated the abundance of 94 chemical compounds in secretion of several individuals, and I would like to have the chemical distance between 2 individuals as expressed by the relative euclidean distance. Some compounds are in very low abundance whereas others are in high abundance,

I am having problems using the /lme /command to fit mixed models. I have a data set similar to longitudinal data, except the hypothesised correlation is between observations taken from different individuals in the same family rather than from the same individual at different times. As soon as I try to specify any correlation structure other than independent, I get the error message

DeaR ComRades, This is a quote from a News article in Science's 11-February issue, about competitions to model data: "For Chris Raimondi, a search-engine expert based in Baltimore, Maryland, and winner of the HIV-treatment competition, the Kaggle contest motivated him to hone his skills in a newly learned computer language called R, which he used to encode the winning data model.

I've read through what I think is the entire thread and looked at the standard in its current incarnation (https://reactor-core.org/~djw/ogg-tags.txt). I have only one major problem with the proposed standard at the moment. The existance of both PERFORMER and ENSEMBLE tags. I think this is describing the same type of data (ENSEMBLE = thing that performed the music, PERFORMER = thing that

With the current version of the "raster" package (that I maintain), R CMD check on packages "soilDB" and "PopGenReport" have this NOTE: Package: soilDB Check: data for non-ASCII characters New result: NOTE Error in .requirePackage(package) : unable to find required package 'raster' Calls: <Anonymous> ... .findInheritedMethods ->

I am writing a rails app with my colleague who wrote a lot of the tests. He had to take a leave of absence due to a death in his family, and I am needing helps with changing the model so that the tests will pass in our spec file. Here is the model: class Worker < ActiveRecord::Base attr_accessible :first_name, :last_name has_many :writings end Here is the spec:

Hi everyone, Would somebody please explain (or point me to a reference that explains) the following error: "Error: object of type 'closure' is not subsettable" I was trying to use rep() to replicate a function: > example_function <- function() { return(TRUE) } > rep(example_function, 3) Error: object of type 'closure' is not subsettable But I just cannot

2nd Workshop "Ensemble Methods" Max Planck Institute Tuebingen, Germany March 4-5, 2005 The second workshop on ensemble methods will take place at the Max Planck Institute Tuebingen (Germany) on March 4-5, 2005. This workshop is jointly organised by the German working groups "Computational Statistics" (IBS-DR) and "Statistical Computing" (GMDS) as well as the

Hello, I am working with a matrix of multilocus genotypes for ~180 individual snail samples, with substantial missing data. I am trying to calculate the pairwise genetic distance between individuals using the stats package 'dist' function, using euclidean distance. I took a subset of this dataset (3 samples x 3 loci) to test how euclidean distance is calculated: 3x3 subset used

Hi All, I am trying to start R Server to run some Java Script in my local machine using the library, 'Rook'. I use Windows 7. And my codes are following, > library(Rook) > myD3dir <- 'D:\\STUDIES\\Java script\\d3-master' > s <- Rhttpd$new > s$start(quiet=TRUE) and i get the following error for the above line, Error in s$start : object of type

Dear R-experts, Searching the help archives I found a recommendation to do multivariate outlier identification by mahalanobis distances based on a robustly estimated covariance matrix and compare the resulting distances to a chi^2-distribution with p (number of your variables) degrees of freedom. I understand that compared to euclidean distances this has the advantage of being scale-invariant.

The rms ("Regression Modeling Strategies") package has undergone a massive update. The entire list of updates is at the bottom of this note. CRAN has the update for linux and will soon have it for Windows and Mac - check http://cran.r-project.org/web/packages/rms/ for availability. This rms update relies on a major update of the Hmisc package. The most user-visible changes are:
