So Stanny did not need to change the argument to 0.95 because it is  
already that value by default (per the summary.Design help page) , but  
experimentation shows that she nonetheless got an error of this sort:
 > plot(s, log=TRUE, at=c(.1,.5,1,1.5,2,4,8), conf.int=0.9)
Error in confbar(nbar - (i - is + 1) + 1, effect[i], se[i], q = q,  
type = "h",  :
   unused argument(s) (conf.int = 0.9)
