Hello, I'm a student at Zlatko Trajanoski's Bioinformatics-Workgroup at the University of Technology Graz, Austria. My master thesis deals with normalisation methods for cDNA-microarrays and statistical analysis. The goal is to implement a free Java-library (and additionally a GUI) to do these steps of processing. I've searched through many parts of R-code (marray* - packages) and that's exactly what i need (input, plotting, normalize,...). But how can i translate/convert the R-code into Java-code without proper knowledge about the R-language? Have you got any experience with such problems? Any further information would help me! Thanks a lot for reading my mail, best regards, Roland Pieler

Why would anyone want to do that? Sounds like reinventing the wheel. A better approach seems to be to write your GUI and DB interface in Java, and then call the R engine with the appropriate R-libraries to do the hard work. R offers infrastructure for that, see SJava (http://www.omegahat.org/download/R/packages/), although I have no significant experience with that.

Hmm, don't think one can translate between two languages without knowing both ... > Have you got any experience with such problems? > Any further information would help me! Why would you want to re-create the stuff that's already in R? Wouldn't it be better to build on top of what we already have in R? Is a RJava interface that allows to got from R to Java and back, hence you can embed R in Java, so building a Java GUI on top of R is possible.
