similar to: [AustinJUG] Problem calling rsync from java on OSX

rsync and ajug lists, been pulling my hair out on this one. i have some java code which uses the Process object to spawn an rsync connection in --daemon mode. the exact same command executes properly when run from outside java (i.e .on the command line) on osx. it also executes correctly from within java on linux using a similar jdk (sun 1.4.1 vs sun 1.4.2 for osx) here is example code:

Hi everybody anybody knows how to talk with R like shown in the Java-Code above? Perhaps someone can help, or tell me its not possible. /* * Java_R.java * * Created on November 11, 2003, 5:36 PM */ import java.io.*; /** * * @author markus */ public class Java_R { /** Creates a new instance of Java_R */ public Java_R() { } /** * @param args the command line

Im doing an aplication in Java and i have a program made in R what i want to launch with Java. I have the following instructions: Runtime r = Runtime.getRuntime(); try { System.out.println ("Llamada a R..."); p = r.exec(sRutaR); } catch (IOException e) { System.out.println ("Error lanzando R: " +

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) {

I don't understand the following behavior for a simple S3 class. The auto-printing at the command line doesn't behave as I expect. I'm probably missing something, but it might be a bug. > print.testClass <- function(x, ...) cat("Class:", class(x), ":", x, "\n") > structure(1, class = "testClass") Class: testClass : 1 > print(1 *

So google for a solution to this problem and found myself here: http://groups.google.com/group/rubyonrails-talk/browse_thread/thread/eaa34998a74831b4/58b80fe0d4eadb1a?lnk=gst&q=+how+to+monkeypatch+Hash%27s+%5B%5D%3D+method+#58b80fe0d4eadb1a But while reading, and admittedly not quite getting the solution, I had a bright moment to balance out the stupid moment, realising that [] = already has

I edit two files named test.h,test.cpp as follow: ///////////////test.h////////////////////////////////////////////////////////////////class TestClass { private: int fTotal; public: TestClass(); ~TestClass(); };///////////test.cpp/////////////////////////////////////////////////////////////////////////////#include "test.h" TestClass::TestClass() { fTotal = 2; }

Hi the list: I can not create R process from Java application with my linux box, the process never was created, or just terminated immediately after I called Runtime.getRuntime().exec(...) The command lines I have tried are(the paths are all correct): "/bin/sh /usr/bin/R" "/bin/sh -c /usr/bin/R" "/usr/lib/R/bin/exec/R"(also set R_HOME=/usr/lib/R) I

Hello, I am the maintainer of the stringkernels package and have come across a problem with using S3 objects in my S4 classes. Specifically, I have an S4 class with a slot that takes a text corpus as a list of character vectors. tm (version 0.5) saves corpora as lists with a class attribute of c("VCorpus", "Corpus", "list"). I don't actually need the

Hi, I'm trying to create a package that contains reference class definitions from which users can create reference objects, but there seems to be something awry. My toy example creates an empty package via package.skeleton('TestClass') to which I add the following R code: TestClass <- setRefClass('TestClass',fields=c('name')) Unfortunately my R console output

Hi R friends,   I'm still studying S4 classes and I have a question about slot assignment. Why would I have to use a special setter method [example 2 below] if I can assign data to a slot directly when I call new() [example 1 below]?   ## first way to do it (the idiosyncratic way?) setClass(Class = "TestClass", representation = representation(myDf = "data.frame"))

Hello, I need to call R from a java(swing) application. I manage to do it with something like : Process p = Runtime.getRuntime().exec("R --slave") OutputStreanWriter o = new OutputStreamWriter(p.getOutputStream()) o.wrote("...") ... etc but at the end no .Rdata file has been created and there are some data I don't want to reload each time (for time execution reasons).

Hi all, this is my first post in R devel? sorry if I lost some of the guidelines. Anyway this is my problem: Version: R version 2.15.2 (2012-10-26) Platform: x86_64-apple-darwin9.8.0/x86_64 (64-bit) I want to make an S4 class that use the output object of the function of nls.lm as a slot: setOldClass("nls.lm") setClass ( Class="TestClass",

Is it possible to override the $new(...) in the reference class generator? I have tried adding a "new" method to the methods of the class, but that is obviously not correct. I have also tried adding it to the class generator, but the class generator still uses the default constructor. As a simple example, this is the current interface: TestClass <- setRefClass

When a reference class method is accessed with .self$x, it has different behavior from .self[['x']]. The former copies the function to the object's environment (with some attributes attached), and the latter just return NULL (unless it has already been accessed once with .self$x). Is this how it's supposed to work? Here's an example that illustrates:

Hi, the following Code demonstrates an possibly Error in R (or you can explain me, why this happens, thanks in advance) Code: ##################################### testClass <- function( stackData= c()) { list( write= function( ...) { sChain= "" for( s in c( stackData, ...)) { sChain= paste( sChain, '"', sub( '"',
