Hi the list, I use rgl to produce a 3D graph. I would like to "show" this graph to some collaborator. Is there a way to save it and send it to someone else? Christophe Genolini

In the source code perhaps? :-) You can find a pretty precise description in the article Robert and I did in JCGS. Actually its pretty simple. Functions have access to the variables which were in effect when the function was defined. f <- function(x) { g <- function() { x * x } g() } The body of g has access to "x" even though it is not global and not passed as an argument. Pass...

JSS, which is at http://www.jstatsoft.org, publishes statistical software with manuals, as well as papers describing, comparing, and evaluating statistical software. Abstracts of all contributions accepted in JSS are published in printed form in JCGS. Although we publish software written in any language, we especially welcome software written in R. The general idea is that packages written in R can be documented in both "R News" and in JSS, but that generally the description in JSS will be more extensive and more seriously peer-rev...

Suppose we start with data("Titanic") mosaic(Titanic, shade = TRUE) How do I combine the dashed box contours of shading_Friendly to indicate negative residuals, with three levels of gray: dark for abs(Pearson Resid) > 4, lighter for 4 > abs(Pearson Resid) > 2, and lightest for bs(Pearson Resid) < 2 ? Thanks, Michael ______________________________________________

Dear R-users, The numerical integration example given in Gentleman and Ihaka (2000), "Lexical Scope and Statistical Computing," JCGS, 9, 491-508, is very interesting and helpful in understanding how lexical scope is about. However, I got some questions that I just can't figure out. First all, allow me to copy the two functions given by the authors: midpoint <- function(f, a, b, n=100) { h <- (b - a)/n (b - a)...

...lysis. As a result, the most significant uses of LispStat have been statistical systems such as Arc and ViSta. In the work I've done with LispStat, ViSta's spreadplot architecture is the best example of LispStat being used to implement a statistical (sub)system (described in a forthcoming JCGS paper by myself, Pedro Valero, Richard Faldowski and Carla Bann). The weaknesses of LispStat are: 1) No high-level analysis modules 2) No standards for data sets, models, etc. 3) No user-oriented data manipulation language 4) Totally inadequate documentation 5) Poor or non-existant printing 6) N...

Dear R People: On the functions qqnorm and qqline, (found in the base package), what are the references, please? This is R for Windows, Version 1.4.1. Thank you so much!

Dear List, this may be a little off-topic, but I failed to obtain the "mother of R"-reference through a couple of library services... Maybe someone can provide me with a PDF?

http://www.jstatsoft.org JSS is now up to Volume 11. This year is the first multi-volume year, with three volumes so far. JSS now has its own ISSN number and its own CODEC. A JSS LaTeX format will become available soon. JSS is aiming to become an (electronic) ASA journal, independent of JCGS, soon. It's contents, including back issues, will also soon be in CIS. Recent volumes of JSS illustrate the fact that R is, indeed, the lingua franca of computational statistics. Many CRAN packages have their corresponding JSS articles. And I hope more package authors will follow. As far as I...

One of my colleagues has a data set from a two-level nested design from which we would like to estimate variance components. But we'd like some idea of what the inevitable outliers are doing, so we were looking for something in R that uses robust (eg Huber) treatment and returns robust estimates of variance. Nothing in my collection of R robust estimation packages (robust, robustbase and MASS

Hi all, Has any of you implemented code for non-negative matrix factorization to solve Y=T P' +E; dim(Y)=n,p ; dim(T)=n,nc; dim (P)=(p,nc); dim(E)=n,p where T and P must be non-negative and E either Gaussian or Poisson noise. I'm looking for two variants: 1. Easy (I think), T is known (that is we just want to solve the general inverse problem) 2. Harder (?), T is unknown (under some

Hi I heard so much about Emacs and ESS that I decided to try it out - but I am stuck at the beginning. Is there anywhere a beginners manual for Emacs & ESS to be used with R? even M-x S tells me it can't start S-Plus - obviously - but I want it to start R... Any help welcome (otherwise I will be stuck with Eclipse and R) Rainer -- Rainer M. Krug, Dipl. Phys. (Germany), MSc

Dear R-helpers, Im trying to fit a Log-linear model on a dataset with bird counts from 60 sites over 14 years for 12 months each (factors for the models). One of the aims is to predict the missing values in this dataset with model predictions. Ive first tried to work with GLM's, that worked fine except for models with one or more interaction-terms. The GLMs run, run .. for hours. So I
