Hi Simon, Thanks so much for your help. Your advice has been taken to heart. I now pass in blocks of 100,000 records, and it does 100,000 predictions in seconds and returns a logical vector with the predictions to an int array. It works like a charm! I want to reference what we were talking about earlier. Let?s say we evaluate an R expression. Is there a way to just print, verbatim, what R

Hi all, I am using JRI with the XTS library. Rengine rEngine = new Rengine(new String [] {/*"--vanilla"*/}, false, null); rEngine.eval("library(xts)"); When I create an xts object, using previously assigned double/date arrays with roughly 5000 elements, the eval method needs very long (up to a minute) to return. I would like to understand what is going on, but I find no

Hi, I want to call R from within Java, using jri as per http://www.rosuda.org/software/jri/ So I am following the instructions in the README file for JRI 0.2-4.

Hi all, I am writing here because the JRI mailing list seems abandoned... maybe some of you guys know an answer or has a pointer into the right direction. I am quite confused by the jars that exist between rServe, JRI and rJava. What I want to do is simply using a local R instance from Java and I thought (and still think) JRI is the way forward. I did the following steps: 1) Installed

Dear R-Help, I am trying to get JRI (the rJava interface allowing Java to connect to R) to work. I was able to run it a week ago when I was doing some testing using Java 1.5. However, I am developing a GUI application using some of the new Java 1.6 features and I just can't get JRI to work with this setup. Here is what I get: Cannot find JRI native library!

Hello All I am trying to get the JRI examples from rJava to work on Windows XP and failing. (And as a more general and connected question is there any review/summary of front-end software for R?)

But

Hi all, It is my first time to use the R-help mailing list and doesn't have too much R acknowledge. The reason that I am writing this email is looking for helps of using JRI in Java Axis Web Service.
