First attempts to use jri on ubuntu 20.04 stranded.
Steps I followed:
1) download rJava from https://www.rforge.net/rJava/files/
2) create a symlink /usr/lib/libjvm.so to /usr/lib/jvm/java-8-openjdk-
amd64/jre/lib/amd64/server/libjvm.so3) configure and make jri4) create
a symlink /usr/lib/libjri.so5) put the built JRI.jar in local maven
repo6) include a dependency to the jar7) create and run a hello world
test for Rengine
The test fails because com.misc.Unsafe.prefetchRead isn't found. As
Iunderstand depending on com.misc.Unsafe.* is a risk.
I will not follow this route any further for now, though I still
thinkhaving jri available would be great. Steps to get there are I
think:
1) remove com.misc.Unsafe usage from the solution2) make libjri
available in repositories (apt, yum, other)3) make JRI.jar available in
maven central
Bye, Eduard

r from javaDate: Sat, 28 Nov 2020 11:57:49 +0000
Thanks all, I'll go for https://www.rforge.net/JRI/ and the
librariesinmaven https://search.maven.org/search?q=jri
The maven library is build from here
https://www.rforge.net/rJava/files/ back in 2017.After this no new libs
are published to maven.It would be nice (understatement) if publishing
new rJava componentstomaven becomes a regular part of R deveopment
processes.This would promote R use from Java which I think is good.And
of course I can help.Bye, Eduard-----Original Message-----From: Abby

This doesn't answer your question, but may be relevant.I have a java-
based application that works on a similar principle.(The
codeishorrendously bad and most of it should be thrown away).I'm
planningto write a terminal emulator, in the nearfuture.(Currently,
secondplace on my top-level todo list).The primary objective is to
buildobject-oriented and messagepassingAPIs on top of the core
terminalemulation system, with at leastsomecross platform
functionality.Notingthat, in my opinion, the cross-platform aspect is
moreimportant for R,than in many other IPC topics.Hence, I'm interested
in hearing"wishlist" items for
suchAPIs.______________________________________________R-help at r-
