Is anyone aware of a mechanism by which I could execute an R function from within java (say a servlet). thanks Richard Piper -- Intensive Care Unit, RNS Hospital, Sydney.

Suppose one wanted to build an R wizard for packaging... One would need to specify and create: package-name/ package-name/Description package-name/INDEX package-name/R/ package-name/man/ package-name/src/ >From this, we'd "probably" like to: - script-up the Description - provide a script for regenerating INDEX by calling out to the

Duncan - (but sent to R-devel, for any other thoughts?) How do you envision RSPerl being used? Without having seen the details, I can think of playing with strings; is there a preferred incantation for stringification of R objects (serialization)? (actually, the main problem I'm having is that I know how I want to code something like: Robject <-

As far as I can tell, there are no facilities in the "base" R for image analysis. Is there any extension or package for R that implements image analysis? I'm thinking of features such as o Reading and writing image files, o displaying indexed or "true color" images, o resizing, cropping, etc, of images, o filters for manipulating images (smoothing, edge detection, etc) o

Dear R users, I have to catch a nasty bug and would appreciate any advice or help! I get a segfault (core dumped) that happens in one of my own functions. The problem is, it does not happen most of the time, only sometimes, so it's very hard to reproduce. Or it may run ok in interactive mode, but bug out in batch mode. Also, it tends to happen more on the slower of my 2 machines (PII 266),

Hello, I checked mail list archives and this topic came up before in March '99 (about ability of R to multithread). At that time rossini at biostat.washington.edu (Tom Rossini) suggested to check his web page in a few month as it was on his list to-do. I checked but the web page is not valid. I wanted to know if in general progress has been made in the area, or if it is planned. I was also

Dear all, Are there functions or packages in R that can handle interval-censored data? I have looked in various packages (such as survival5 or event), but it seems that only right-censored data can be analysed. More generally, are there methods to analyse both interval-censored observations and right-censored observations in the same data set? Thanks in advance. Emmanuel Paradis

Hi all, I am considering writing a 3D visualisation package for R. Purposes: - Visualise 3 dimension data - Manipulate the data or series or any other object with the mouse as in any 3D software (3D Studio Max, Lightwave...) - Eventually display more than just 3D objects. Justification: - It's always interesting to plot data before performing any analysis - Manipulating (rotating,

I am trying to use on ESS win XEmacs on Windows, but I don't know how to tell XEmacs that use the ESS, I don't found the .emacs file and the system don't let me create such a file.

Hi, I am new to R, but a fairly `old' user of Stata. I read posts asking about survey methods and large datasets in the archive, so I will not ask those questions again. But some still remain: - R seems to consume more memory given the same set of data, say if I have only a data frame defined, than Stata. Am I right if I think that this is because the object oriented nature of R and can

Hello, I carelessly sent this to the unfortunate Mr. Johnson, rather than to the list, so I'm sending it on to the list. Re-reading it after a couple days, I think that it might still be worth sharing. I think I agree with an earlier reply: GUI's are confining, and eventually slow you down, relative to programming. The strong point of a GUI is that it lets you quickly, easily do a new

Hi all, I caught a passing reference to PMML on the WEKA list (I think) .. an XML way of communicating 'data mining models'. I am of the opinion that XML is a 'good thing' and I would for instance like to see a standard XML way of communicating the content and context of datasets (eg of timeseries) but it has been a long day and my internet connection is slow and so I have

we still do not have dynamic graphics in R natively. i just found out about a widget library called fltk info is at www.fltk.org it has all the stuff r currently can do only through tcl/tk or (as i do it) excel: sliders, knobs, spinners and so on. it is multiplatform, there are production versions for unixen and windows, and there is a beta for macs. this could be a way of getting some of

Hello- Tired of the crashes I was experiencing with r 1.2.1 on Windows ME, I downloaded the r-1.2.1.tgz under my Debian Linux box. I untared, unzipped and then I ./configure and make as specified i the FAQ. But something went wrong...I had version 0.90 per-installed, as it comes with the normal Debian distribution and now, whenever I run R, the old version is the one that executed. Can

As a user of only R, I don't use much of the potential of ESS and Emacs. Without entering a religious feud, is there any reason I should use XEmacs rather than my current GNU Emacs? (I looked on the XEmacs site, but I didn't understand the programming issues they were talking about (over my head).) Martin Henry H.

Dear R listers -- The program below does the following tasks: 1. It creates a file (wintemp4) that is a subset of alldata4 consisting of "winner" records in 50 industry groups (about 5400 obs); 2. It defines a function (myppr1) that runs the ppr function in modreg once to generate goodness of fit (sum of squared errors) measures by number of terms included in model and then reruns
