R and/or REngine kills Java
Hi all,
I am using R and JRI under Windows XP Pro. I am posting this question
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

Hi,
Forum newb here, looking for some help. Have been trying to install an

JRI and XTS library
Hi all,
I am using JRI with the XTS library.
Rengine rEngine = new Rengine(new String [] {/*"--vanilla"*/}, false, null);

I would like to understand what is going on, but I find no

failing. (And as a more general and connected question is there any
review/summary of front-end software for R?)
I have installed rJava from the Windows binary supplied. I compile and
run the example supplied (rtest.java) and get the results below. I do
not think the notes about a deprecated API are a problem. But
