How do you do that? For R's own executables on Windows R_HOME is determined from where they are loaded from. You cannot AFAIK determine from within an executable where the R.dll was linked from. That's why the rproxy.dll uses the registry. I believe you have even less information on Windows. Brian -- Brian D.
