`labels` is for labels, `at` is for tick (and label) locations. They  
should be the same length. One label for each tick location. As  
described on the help page. Unless you have a different understanding  
of `labels`. I was confused for a long time because `ylab` and `xlab`  
are not really for labels but rather for axis "names".
