I tested various flags but I cannot find the correct syntax. for now, my latest attempt was ``` rm -rvf?

Dear All, I'd like to write a little application in java wich should pass some commands and data to R and displays the results (tables and charts) in a java frame. First I wanted to work with Omegahat's SJava but had lots of issues already at the installation.

Hello, I want to import R-output via Rserve to Java, especially for the function ctree from the package party. Rserve is working properly. Yet, I only get the predictions with the Java code try{ RConnection c = new RConnection(); ... c.voidEval("modell <- ctree(...)"); REXP y = c.eval("nodes(modell,1)[[1]]$prediction"); ...

Hello All, I am trying to get cluster heatmaps using R from Java in my application. I got the Rserve using which I am able to make TCP/IP connection to R. I am trying to send a double[][] array (say 5x8 dimensions) to R and convert it into matrix using as.matrix() function in R. Is it correct to do this? Can I directly pass this array to dist() function to generate the distance matrix ? if not

Hi, my c++ code have to call some functions coded by java. In the beginning, I call those functions by jni. Unfortunately, jni has lots of performance loss, so it can't meets my needs. I wandor if I can convert these java codes to c/c++ by llvm. First, I convert java words to llvm bytecode, then covert llvm bytecodes to c/c++. I am a green hand of LLVM and compilers. So tt's very

I'd be happy to (help) port the source to Java. How many lines of code are we talking?

Hi everyone, I'm planning on releasing Speex 1.2beta2 in the next few days. I'd appreciate if everyone could try and test the current svn to make sure no bug crept in for your favourite plarform/application. Cheers, Jean-Marc

You probably want to sit down and have a long talk with Jeroen Frijters, the principal behind the IKVM project. Note that you will have to deal with ClassLoaders at some level, regardless of what you'd prefer. > A more obvious problem is, of course, that it is not possible to > compile Java code statically and save the result in the disk. > That is untrue--last time I checked, gcj

Hi, When using the libguestfs-java bindings, java.library.path should point to the place the JNI stuff resides in. In [1] it was suggested to set it to /usr/local/lib but apparently, it is deployed elsewhere in other distributions, right? so I wonder what is the recommended way of setting it in a Java application that could execute on various distributions. Additionally, the libguestfs-java
