We have finally configured the R-Java interface as a `regular' R package. This allows R users to create arbitrary Java objects and call any accessible method. It has a reasonably sophisticated mechanism for handling transferring of arguments from R to Java and vice-versa, and allows Java classes to be implemented via R functions. The package and all the documentation is available from

I like to have a continuously running R process, which can receive a dataframe from a client (over TCP/IP), does some processing, and sends some data back. What is the prefered way to do this? Using the socket interface? Using omega's CORBA stuff? Does anyone has example code for doing so? Thanks for any help Regards -- Dr. Jens Oehlschl?gel-Akiyoshi Analyse MD FACTORY GmbH Gr?nstr. 15

Hi, I need to somehow make R communicate with another remote JAVA process which provides compute services. I have control over the communications protocol, but I would like to keep it to a standardised protocol, such as SOAP, CORBA, etc. What I would like to know is, what do other people use to do this? The nature of the communications will be low bandwidth procedure calls, with little data.

Hi, I just had a very quick look at the StatDataML proposal --- nice work! At the risk of showing my ignorance, I want to mention my first impressions. My first impression is that defining datasets in terms of arrays and list is a bit too high a level. What about simpler vectors, scalars? (I know that R/S don't have scalars, but other systems/applications do.) Can we think of a core

I've just installed Mandrake Linux, then compiled R-0.65.1 . Whether because I omitted some necessary items when I selected software for installion, or because they anyway needed to be loaded afterwards, I found it necessary to load the following packages in order to compile R-0.65.1 pgcc-g77-1.1.3-3mdk.i586.rpm (Fortran g77 compiler) XFree66-devel-3.3.5-3mdk.i586.rpm (X.h etc

Right. The methods such as as.data.frame.numeric don't get dispatched, basically because RSMethods tries to interpret class(x) in the S4 sense (so, e.g. a numeric vector has class "numeric"). Problems can then come from different semantics for S3-style and S4-style methods. The older methods don't dispatch on the mode of vectors (or equivalently, on the value of

Hi folks, I need your opinions on a basic design issue. I''ve seen the light of RoR and have replaced my Perl (DBI/CGI) based web server <-> RDBMS communication with RoR, but I still have a whole host of users (other servers/OS''s etc) out there wanting to talk to my RDBMS and they only talk Perl. Also they don''t want to talk Perl/DBI directly (they are not allowed

Dear Friends, I'm trying to learn to use parallel computation using snow & rpvm Now, I have two boxes: 1) Pentium 4, pvm 3.4.5, R 2.2.0 with FreeBSD 5.4 (box uffbsd); 2) PowerPC, pvm 3.4.5, R 2.1.1 with Debian Linux latest stable (box powerpclinux); I'm using the instructions in (found in snow.pdf) http://www.stat.uiowa. edu/~luke/R/cluster/cluster.html.

Hallo, I'd like to write a GUI (first choice with GTK+). I've surfed through the R- an Omegahat-Pages, because I'd like to use RGTK2, GTK 2.10.11 in combination with glade on Windows XP (perhaps later Unix, Mac). I've found a lot of different information. Because of the information I'm not sure, if this combination is running on Windows XP and I'm unsure how it works. Is

I didn't see any mention of this in the material on CRAN. The two S.h files define R_problem_buf as a real symbol rather than simply declaring its existence. As a result, a shared library that links two or more files that include this will get duplicate symbol complaints. Since it is not defined elsewhere in the code, someone has to define it. A secondly thing is the documentation for .C()

Hi, About GUI and R, I would say that personnaly, I need to build a nice GUI for people who does not know anything about R, to conduct simulations. I don't know if the choice of R is the best. Maybe writing all the code in Java would be better... I don't know. That's why I have tried to install RSJava from Omegahat on my computer (Windows 2000). With R 1.5.0 or 1.5.1, I get the

I have finally got around to putting 4 packages on the Omegahat web site for use on Microsoft Windows. The packages are: RDCOMClient - interactive, dynamic access to arbitrary (D)COM objects from within R that allows one to create COM objects from R and call their methods and access their properties without the need to compile any code specific to the COM object. RDCOMServer - facility for

Is there a way to programmatically determine how many arguments a function accepts? In S, one can compute this as length(theFunction) - 1 and determine the parameter names as names(theFunction) due to the representation of functions. (Just in case anyone is thinking of nargs(), that is just for particular calls and does not concern itself with the function definition.)

For those who are interested, I've finished release of 0.4 of pmg and have placed it on my website at http://www.math.csi.cuny.edu/Statistics/R/pmg. The pmg package provides some GUI elements using the RGtk package and friends: RGtk, OOP, RGtkExtra, RGtkHTML, RGdkPixbuf, RGtkViewers and REventLoop from www.omegahat.org and gtkDevice from CRAN. (These require a form of UNIX such as linux, OS

Hi, I had some Java code that worked with SJava 0.65 under R 1.8.*. I'm trying to get it to work with R 2.0.0. My JVM is Sun 1.5.0 (running on Fedora Core 2) I downloaded and installed SJava 0.65 in my personal directory using R CMD INSTALL SJava-0.65.tar.gz -l ~/src/Rlibrary and before starting R I sourced RJava.bsh.
