Getting JRI/rJava to work
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?)
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

work with this setup.
Here is what I get:

rJava fails compilation on R-2.9.1 but not R-2.7.1 on Debian Lenny
I have been futzing around for days tying to get rJava to install on

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
