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()

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.)

Thanks for your help Duncan. Your last comment helped me to figure out what FreeBSD was doing differently than Linux/Solaris. This fix worked on a machine with Python 2.1, R 1.3.1 and FreeBSD 4.1. Here are the details: The pthreads fix: I added '-lc_r' to the PKG_LIBS definition in src/Makevars.in. The FreeBSD 'man pthread' page suggests that adding -pthread to the gcc statement

Dear R-helpers, I run R version 2.8.1 (2008-12-22) on i386-apple-darwin8.11.1 I would like to call R from Java. I downloaded SJava_0.69-0.tar.gz, and then issued the command suggested on http://www.omegahat.org/ RSJava/ : % R INSTALL -c SJava_0.69-0.tar.gz ARGUMENT 'INSTALL' __ignored__ WARNING: unknown option '-c' ARGUMENT 'SJava_0.69-0.tar.gz' __ignored__ I then

Dear Expects, I tried to install the SJava package to the Library subdirectory of my R1.5.0. However, when I tried it according to the instructions from http://www.omegahat.org/RSJava/, I got the following error messages: library(SJava) Error in .Defunct() : `.Alias' is defunct. See ?Defunct. >.JavaInit() Error: couldn't find function ".JavaInit" I downloaded SJavaWin

Just a note to complete this thread regarding the RSPython package. A binary version for this package is now available for Windows, compiled against R-1.4.0 and Python 2.2. Also makefiles and instructions are provided for compiling it oneself. It currently works only for one direction, namely embedding Python within R. As time permits, I'll add the embedding of R in Python to make it the same

I am trying to download and install Omegahat Sjava (http://www.omegahat.org/RSJava) to be able to call R from within Java. The install instructions are as follows: cd $RHOME/src/library unzip SJava_0.69-0.zip cd SJava ./configure.win $RHOME cd $RHOME/src/gnuwin32 make pkg-SJava However, my command prompt won't recognize "unzip","./configure.win", or

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

We're starting work on an R package and corresponding S-Plus library to help programmers write software that will work in both systems. Some descriptions and downloadable software are available on the Omegahat web site, at http://www.omegahat.org/SLanguage/ The strategy, as described there, is to be as back-compatible within R and within S-Plus as possible, but provide tools and guidelines

Apologies, I am a non-techie so am finding installing SJava (which I need for RMAGEML) very frustrating indeed. I am running rw2001 on WindowsXP with Java - jre1.5.0_02. Could somebody please explain to me step-by-step how to install it as I have tried all the help files. The website’s (HYPERLINK "http://www.omegahat.org/RSJava/"http://www.omegahat.org/RSJava/) instructions for

Please ignore my ignorance, I'm new to R, but starting a longish project that will use R a lot. (a computer scientist learning about stats at the same time). Did anybody alreay write a XML parser for R? XML, as we will have tons of data-interchange with all sorts of other programs and XML is good for giving meaning to raw data. I checked the FAQs and the documentation, but didn't find

Hello, I downloaded the R for Java interface. I read about calling R scripts/methods from java, but I can't find any detailed example about this. I need an example of how to use this. For example how to load data object (i.e. of colt) to r , run anova function and get the results - all from java!!! Thank you very very much Regards, Moshe i-impact

Hi, I installed SJava 0.66-1 on my linux RH 7.2 machine. I am using R-1.7.1. I set LD_LIBRARY_PATH up then called library(SJava) and it was fine. But when I called .JavaInit(), I got weird error that states it could not find java/lang/Hashtable. The session is below and shows my java configuration. I am using j2sdk1.4.2_01 from Sun. Thank you very much. Weiming Zhang > .javaConfig

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

Hello all, We currently have a java web utility that allows multi-threaded data analysis using S+. We want to migrate it to R. However, the guy who preceded me here left some documentation indicating that he couldn't implement it because R didn't support threading. Also, he noted that the R-Java interface(org.omegahat.R.Java.REvaluator) wasn't thread safe even if R was. Can

Hi, I have installed the SJava package (see http://www.omegahat.org/RSJava/ ) without any problem. I was able to run the examples (see http://www.omegahat.org/RSJava/examples/index.html ) from R, on my “R Linux server” and directly on the display of the server, But, if I run theses examples on an “X11 client”, under Linux or windows, with a “correct configuration” of the X11 client

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

Dear all, Maybe this has something to do with R crashing? When my R version crashes, there is Rgui.exe still running in the background (i.e. W2K's task manager recognises it only as a process, which apparently is using almost 100% of the CPU). I can reproduce that by "using" the SJava package (from Brian Ripley's homepage, as suggested on http://www.omegahat.org/RSJava/).
