Using R in Java?

Wow, very interesting!  The netbeans example looks similar to what I
want, which is based on Eclipse RCP.

I will explore this more, as well as the JRI indirect method suggested
by Christian.

Thanks!

Hi 2 questions-
1. Is there a package that will allow me to run R scripts  
(entirely) from
Java?
2. If so, is there a way to capture the output of those scripts,  
(including
images) and embed them in my SWT java app?
My challenge is I have a java app that does some statistical  
chores- it
would be fantastic if the users could use their R skills to modify  
a script
in whatever R environment they like and then my app could use that  
script to
calculate the results and display them in the app.
I have found StatET and JavaGD with rJava/JRI and read through all  
the
docs... its seems possible that some combination may give me what I  
want,
but its not very clear.

The JRI part from the rJava package does exactly what you want.  
Simple data types like numbers or strings are directly returned as  
java objects. But I'm afraid for the images you have to use the  
files system indirection.

If needed I can post an example,

Christian
