Hi list, The task I am facing is, I need to work on a web interface (which is based on java) for R, user selects statistical methods he wants, then submits them to back R computing engine, the results (estimates or test results) can be returned to user on webpage. The statistical methods may not be simple functions like lm(), ks.test(), but some functions written by statisticians. I checked R-Gui projects http://www.sciviews.org/_rgui/, it seems Rserve is what I want. But there may be other tools. Has anybody done comparisons among these java-R interfaces? Is Rserve stable enough (for all kinds exceptions)? Engineers care more about the system robustness. I would like to hear any comments and suggestions. Thanks, Tib -- I am Tib, not Rob.
