...tion here since the reason might be R related (since I am running an R script) but there is also a very good chance that it is JRI only (since I am using the JRI interface to activate the script) -- in which case I want to apologize for misplacing this message. I have a method that instantiates an REngine object every time it is called. It runs a script provided by a file name and closes REngine afterward. The script works fine, the png file is successfully generated and the PNG file is released so that I can delete it if I want ( but I don't in that case). For some strange reason, when running...

Hello, I am trying to run JRI example from rJava, but I have some issues. I have read many posts and didn't find any solution to my problem. I have the following code: Rengine re = new Rengine(null, false, null); System.out.println("Rengine created, waiting for R"); if (!re.waitForR()) { System.out.println("Cannot load R"); return; } System.out.println("re-routing stdout/err into R consol...

Hi everyone, I try to run my R script in Java, thus I installed JRI. and run the example, I am using Eclipse on 64 bits windows 7. part of the example code is as follows: public static void main(String[] args) { System.out.println("Creating Rengine (with arguments)"); Rengine re=new Rengine(args, false, null); System.out.println("Rengine created, waiting for R"); if (!re.waitForR()) { System.out.println("Cannot load R"); return; } However,...

...nd they seemed to be successful. (See below for the output from make, for example.) But when I try 'run.bat rtest' (with and without R command line arguments) the output that I get is 'c:\temp\r\jri>C:/PROGRA~1/Java/JDK15~1.0_0/bin/java -cp .;examples;src/JRI.jar rtest $* Creating Rengine (with arguments)' That suggests that it gets to line 60 in rtest.java then stops on line 61, without producing an error. Line 61 is Rengine re=new Rengine(args, false, null); so it seems that I am not able to construct an Rengine. Can someone suggest what I might try next to track down the...

Hello everyone I am currently developing a web based R script editor. My idea is to pass the R script command as a string into the backend , then use the Rengine instance to parse the R script command and get the resutls. Do anyone know how to use Rengine instance to parse a R script String? if so, could you give me a small example (in Java)? i really appreciate. -- View this message in context: http://n4.nabble.com/how-to-use-Rengine-instance-to-parse...

Hello once again, After locating the standalone REngine object set, I am having difficulty integrating them into the XCode project I intend to use them in. Suppose one started with the REngine standalone source and a blank XCode file, what special modifications need to be made to allow the source files to see inside R.framework? Importing the...
