I don't know if this will help you. Just thinking about your reasons to use windows, maybe it's because you need to execute some windows program. My solution is to use R-GRASS in Linux for simulation, what is excellent beacuse of the wealth of R functions for statistical evaluation of the models, and the matrix operations in R. Also you can call C compiled code from your R script to speed up bottlenecks in your code, as pieces with a lot of loopings etc. And if you need to execute some windows program, you can also execute them remotely in a windows machina via ssh and get bak your results to your linux machine. This also works right. Good luck Javier ----------------------------------------
