using weights=varIdent in lme: how to change reference level of grouping factor?

I have spent some time delving through the guts of lme() but haven't figured it out yet. I'm somewhat baffled, as the default order of factor() should be Female, Male in any case, so I don't see where the order could be getting messed up.
Hi Ben, Thanks for having a look at this. I think lme is using the category with the largest number of observations as the reference level. I have no idea how to change this. Emma
