I have received a few private emails asking for some simple demonstration of calling Java code from R using the rJava package (which can be installed directly inside R). Here is one example for convolving two vectors (an example in the R manual about linking C with R). First write a Java program public class my_convolve { public static double[] convolve(double[] a, double[] b)

I think remember this error from trying to write an Excel file that already existed. If this file already exists, try to delete it and see, if this solves the issue. Besides that you're writing that you are "Using write.xlsx to extract data from an Excel file", write.xlsx() is to write an Excel file, not to read from it. Should be read.xlsx() then iirc. ? ?

Hello, I have experienced the following problem after installing rJava (it being a prerequisite for another package in which I am relly interested). Any helpful thoughts would be appreciated: OS: Windows XP Professional 2002 SP3, have Java 6 Update 20 from Sun, also installed the JDK from http://java.sun.com/javase/downloads/index.jsp (or at least I suspect I installed it as it asked to re-boot

Not sure if this the right place, but I can't seem to subscribe to the rJava mailing list. Sorry for the noise. I have a jar file in the CLASSPATH variable. On running .jinit and checking .jclassPath, i can see the jar file containing the class. Yet when trying to instantaite the class, i get a class not found error. Now If if, create my own vm (see below), and then run .jinit (which will

Dear all, I got an issue trying to parse excel files in parallel using XLConnect, the process hangs forever. Martin Studer, the maintainer of XLConnect kindly investigated the issue, identified rJava as a possible cause of the problem: This does not work (hangs): library(parallel) require(rJava) .jinit() res <- mclapply(1:2, function(i) {

Hi all! I recently tried to install the rJava package on my notebook (Debian Etch / Kernel 2.6.15 / jdk 1.5.0-5 / R 2.2.1 / rJava ?? the repo one, have a look below). I compiled R myself with "--with-readline=no" and "--enable-R-shlib flags". Now, each time loading the library rJava I encouter the same error. I reinstalled several times (as root), always the same problem:

Dear All, I think there is something wrong with rJava on any Debian based distribution. I may be wrong, but I experiencing exactly the problems mentioned at https://github.com/amattioc/SDMX/issues/130 and at https://github.com/s-u/rJava/issues/110 A couple of packages (RJSDMX and xlsx) are now impossible to install on my debian stretch platform running R 3.4.

Hi list, I'm wanting to use a matrix as input to some java code, but I seem to be unable to do this (See code below). When searching online for a solution I found that rJava 0.5-2 (the version under development not yet in CRAN) is adding "direct support for raw vectors as method parameters". Is this related? I also tried to use .jarray / .jcast in various combinations to no avail.

Hi, Here is a problem we see with the Mac and Windows binaries of rJava (0.9-3) currently available on CRAN for R-devel (i.e. under bin/macosx/leopard/contrib/2.16/ and bin/windows/contrib/2.16/): > library(rJava) > .jinit("gaggle/inst/jars/gaggleRShell.jar") Error in .Call("R_do_new_object", ClassDef, PACKAGE = "base") :

Hi Dirk, It was unclear to me to which extent it is a kernel/security patch vs (r)Java issue. In any case, this is really problematic for me as it prevents me de facto from running some key R packages for my daily work. I'll post again if I see some solution (other than downgrading the kernel) somewhere. Meanwhile, any suggestions for a fix is welcome. Cheers Lorenzo On Mon, Jun 26, 2017
