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 I do not know what causes the unsupported conversion messages. Versions used etc below. Any ideas please? Thanks for any help.
