Not to prejudge the case, but such sometime errors are classic symptoms of access violations in Fortran, such as accessing a variable whose value has not been set, exceeding array bounds, or something similar. The usual suggestion is to recompile the Fortran with ALL error-checking options turned on and see if such a bug turns up. -- Mike Prager, NOAA, Beaufort, NC * Opinions expressed are personal and not represented otherwise. * Any use of tradenames does not constitute a NOAA endorsement. ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
