Trying to create R dataframe with JRI
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:

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

ASCII dump from an REXP (JRI)
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
