Hello, after some discussions with Martin Maechler and Josef Leydold (WU Wien), we have felt the need for some package that should allow for an object-orientated approach to distributions. Our small group at Bayreuth now has developed a package "distr" which tries to fill this gap, implementing distributions by means of S4--classes. A mother class "Distribution" is

Hi R-devels, in "Writing R extensions" as well as in the help to .onAttach(), you mention that one could use this function to issue a start-up message/banner for the package. My little wish for Easter: a 'quietly'-type argument for .onAttach() / .First.lib() which is passed through by functions require() and library() respectively, and by means of which one could optionally

Dear R-devels, We have encountered a problem concerning a dead lock in the dependency graph: We have two packages A1 and A2 where A2 extends A1. We have one package vignette for both packages, but which should be included into package A1. So in the "suggests" field of the DESCRIPTION file of A1 we suggest A2 to be able to produce the vignette at build/install time. On the other hand

Hello, I'm getting some error messages from R CMD check I can't deal with. I'm working under Linux with R 1.8.1 The package working directory can be found at: http://www.uni-bayreuth.de/departments/math/org/mathe7/DISTR/distr.tar.gz Here's the 00check.log produced by R CMD check distr * using log directory '/home/tom/studium/R/swp/swp/package/distr.Rcheck' * checking

Dear all, I have a question regarding setIs and method dispatch in S4 classes: Consider the following example: ##################################################### ## A02 "contains" A01 by setIs: setClass("A01", representation(a="numeric",b="numeric")) setClass("A02", representation(a="numeric",d="numeric"))

Hi, Does anyone know what the distribution for the product of two correlated normal? Say I have X~N(a, \sigma1^2) and Y~N(b, \sigma2^2), and the \rou(X,Y) is not equal to 0, I want to know the pdf or cdf of XY. Thanks a lot in advance. yu [[alternative HTML version deleted]]

Hi, as a starting point for using Tcl/Tk in R, I used to refer to James Wettenhall's nicely presented TclTk Examples formerly hosted at http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/ These days I have been trying to reach these pages but without success. Does anyone know (James, himself, perhaps ;-) whether they are / will be available at some other location --- it would be a pity

After some reorganization, we would like to announce the availability on CRAN of a new version (1.6) of our package "distr" as well as the availabilty on CRAN of the new packages "distrEx", "distrSim", "distrTEst", "RandVar". ----------------------------------------------------------------------------------------- Changes from 1.5 to 1.6 -[former

Hi, I noticed a minor flaw in integrate() from package stats: Taking up arguments lower and upper from integrate(), if (lower == Inf) && (upper == Inf) or if (lower == -Inf) && (upper == -Inf) integrate() calculates the value for (lower==-Inf) && (upper==Inf). Rather, it should return 0. Quick fix: ### old code ### ### [snip] else {

Hi, I have problems when calling fft_factor and fft_work directly in my C-code. Martin Maechler already told me that I should not do this -- anyway, the code works fine if the length of the vector is a multiple of 2,3,5. If the length of the vector has different form I get, in some cases, a segmentation fault when work and iwork are freed (I use C's malloc to allocate memory for work and

Martin Maechler asked me to restate my problem. Compiling the file (slightly modified w.r.t. the formerly attached file) that can be found at http://www.geo.uni-bayreuth.de/~martin/filetransfer/xswms2d.Rd terminates with the error message ******* Syntax error: mismatched or missing brackets in /----- ..... \----- when compiled by R CMD Rdconv -t txt xswms2d.Rd However, the file does

Hello, I've stumbled upon following problem, when trying to overload the methods for group Math for an S4-class which contains functions as slots. setClass("NumFunction", representation = list(fun = "function")) NumFunction <- function(f) new("NumFunction", fun = f) square <- function(x) x^2 NF <- NumFunction(square)

As Brian Ripley said this morning on 'r-help', a binary distribution of R 1.0.0 to run on Windows 95, 98, NT4.0 and 2000 on Intel/clone chips is available at CRAN (at least in Wien). The URL is http://cran.r-project.org/bin/windows/windows-NT/base/ See 'README.rw1000' for installation instructions and 'CHANGES' for a list of Windows specific news. As always,

Dear List, I just tried installing R 1.1.1 on SuSE 7.0 and encountered some problems. Using the precompiled binaries, I had a failed dependency: R was looking for "libblas.so.2" and apparently didn't find it. I then tried compiling from sources, which failed with the message: "/usr/bin/ginstall: zero.so No such file or directory" (or something to that effect). I'm

We would like to announce the availability on CRAN of a new package distr . It is to provide a conceptual treatment of random variables (r.v.'s) by means of S4--classes. A virtual mother class "Distribution" is introduced. All distributions of the "base" package are implemented as subclasses of either "AbscontDistribution" or "DiscreteDistribution".
