I know this is an old question, and that it doesn't follow proper etiquette, but since I just spent half an hour figuring out part 2 myself, I thought I could jot the answer down for anyone else ever stumbling across it:

(1) You have to include 'total = TRUE' in your controls (which should, at least by now, be the default though). If you want to have the total column before the others, then also add 'total.pos = "before"'.

(2) You need to also specify the test you want to use for the variable, so for example 'kwt', 'anova' or 'notest'. Then, you would specify it as follows: 'anova(URV.days, "median")'.
