When reading the documentation for the "sleep" data set in R, the impression is clear, this is an "independent groups" kind of design (two groups of 10 subjects each). However, when browsing the original article (referred to in the help file), my impression is quite clear, this is really a "repeated measures" kind of data (one group of 10 subjects, two observations). What is correct?
