ASCII dump from an REXP (JRI)
Hi Simon,
Thanks so much for your help. Your advice has been taken to heart. I now

evaluate an R expression. Is there a way to just print, verbatim, what R

Dear R-Help,

Getting JRI/rJava to work
Hello All
I am trying to get the JRI examples from rJava to work on Windows XP and

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
