Title: "Yxilon - a modular open-source statistical programming language" Author: Uwe Ziegenhagen (Humboldt-Universitat zu Berlin) Abstract: Popular statistical programming language as R and XploRe are interpreted which makes them slow in computing intensive areas. The common solution is to implement computing intensive routines in low-level programming languages like C/C++ or Fortran and subsequently integrate them as dynamic linked libraries (DLL) or shared object libraries (SO) in the statistical programming language. With Yxilon we start an open source project to reimplement the XploRe language to compile directly to a low-level language. The generated C/C++ code and Java code can then be compiled either to DLL's/SO's or stand-alone programs.
