similar to: Executing an R function from Java.

I have been doing some programming with java servlets for data collection. I was wondering if there is a way to connect to the R-server using java to do data analysis. A java-interface or some connection class. I think there is some similar facility with SAS, although I have not looked at it. Richard Piper RNS Hospital, Sydney.

I've been doing some prototype simulations in Python, and my plan at first was to pass the results off to R, but now I would like to make more of an integrated use of the R routines. I'm curious about the use of libR.so, but I'm uncertain, still after having looked through the documentation 'Embedding R in Other Applications' and 'Writing R extensions' how I can

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 <-

I thought I had the Default

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),

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

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

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,

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

Greetings from Switzerland! Are there any plans/initiatives/considerations in future versions of R for commenting out regions via something like " /* */ "? (I've got an application for which something like that would be useful; if not, there are less simple solutions). best, -tony "Commit early,commit often, and commit in a repository from which we can easily roll-back

First let me confess that I am a R-novice. I am trying to fit a beta distribution for a dataset using fitdistr(MASS). I am having difficulties with it because the function tends to fit a distribution with a range of 0 to 1 (I guess). However, my dataset is not! Anytips or tricks will be very much appreciated. Many Thanks. T. S. Ramanarayanan, Ph.D. Aventis CropScience Research Triangle Park,

Dear colleague, Just an e-mail to know if they are people working in the field of chemoinformatic that are using R in their work. If yes I was wondering if we couldn't exchange tips and tricks about the use of R in this area ? Best regards Fred Ooms [[alternative HTML version deleted]]
