R & Java

Hey guys, 

I'm a (Java) integration architect.
We are currently stuck with SAS but I'd be happy to switch that to R! (of
course ;-).
Now, a big argument for the latter, is that we can integrate it seamlessly
with all our existing (java) apps.
Therefore: has anyone heard of a java API (like SAS has it's Java API for
enterprise integration) or a Service we can call (e.g. a web service, a http
invoker service , ...), ... ?

The ideal solution -to my view- would be to integrate it with ESB
functionality (e.g. Mule: http://www.mulesource.org/display/COMMUNITY/Home).
It allows you to stitch/knit/... together what/how/where you want.

Has anyone ever done such a thing?
Thx for advice, 

Regards, 
Philippe

I think you are looking for something like RServe. http://rosuda.org/Rserve/.

It sets up R as a server which you talk to via TCP/IP. It has client
APIs for Java and a number of other languages.

I don't have an answer, but I suspect that if you 
install.packages("RSiteSearch"), you might find information relevant to 
your question from the following: 


 library(RSiteSearch)
java <- RSiteSearch.function('Java')
summary(java)
# Reports that 136 help pages contained "Java", 23 of which are in a 
package "rJava", 16 in "R.utils", etc. 
HTML(java)
# Opens a table with 136 rows in a browser,
# with the "rJava" pages first, followed by those in "R.utils", etc.,
# the last column of which contains links to the HTML versions of the 
help pages. 


      Hope this helps.

I don't do Java personally but there is a lot out there (and I do support
rJava for Debian and hence indirectly on Ubuntu). See the links above and
also google for BioCep which a lot of people dig.
