R help - Aug 2010 - R and Java

Hi folks,

Maybe that is not the best place to ask, but I 'd like some of you could
help me...

I'm using jri to run R commands under Java, by its examples I can eval
expressions, returning single values or vectors to my Java variables. But, I
would like to know how to assign the values of a Java vector (like: double
x[] = {1.7 , 2.8 , 3.4};  ) to a R variable, so I can eval a function using
it (like: mean(x) ).

Someone could help me?

Best regards,

Perhaps you can give some more meat to your question, write some code 
with what you tried, why it failed, etc ... and repost on the 
appropriate mailing list (see above).
