calling r from java (Eduard Drenth)
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 Adrian Adrian Trapletti Steinstrasse 9b, 8610 Uster, Switzerland P +41 44 994 56 30 | M +41 79 103 71 31 adrian at trapletti.org | www.trapletti.org

Now I developed a service that executes Rscript (Using ProcessBuilder), sends text to stdin of the process and reads from stdout of the process. Works fine, but this is inefficient, because every call reloads all that is needed. I have looked into this: https://github.com/microsoft/java-client-library https://rforge.net/Rserve/ several other sources on stackoverflow etc. A lot of these sources seem old or not maintained. Now my question: Is there a preferred and maintained way to efficiently call R from Java? Preferrably available in maven central?
