[R] calling r from java (Eduard Drenth)

[Eduard Drenth]

Because of efficiency? But almost all development I do is in
Java/Xml/XQuery so I am interested in efficiently integrating the two.
And for our small institution it is important to limit the number of
technologies / frameworks.
Bye, Eduard

Hi Eduard,
I recommend separating the R quant code from Java and deploy the R code
as a REST service, e.g. using https://github.com/opencpu/opencpu  

Best regards
