Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. On MacOSX, with R 2.15.2 and JDK6
2. Rsession session = Rsession.newInstanceTry(System.out, null);
    session.loadPackage("robust");

What is the expected output? What do you see instead?
Evaluation of expressions work, but load libraries fail
run:

BUILD SUCCESSFUL (total time: 2 seconds)

What version of the product are you using? On what operating system?
Mac OSX 10.7, JDK 6, R 2.15.2

Please provide any additional information below.
Interestingly, I have a Macbook Pro and iMac, with the same configs. The same 
programs works on the Macbook Pro but fails on iMac. Still haven't figured out 
what caused the issue.

This might be due to a previous running instance of Rserve which needs to be killed befaore launching a new proper one.
