     The 'sealevel2' data frame has 81 rows and 3 columns. The first
     two columns contain annual sea level maxima from 1912 to 1992 at
     Dover and Harwich respectively, two sites on the coast of Britain.
     The third column is a logical vector denoting whether or not the
     maxima in a given year are assumed to have derived from the same
     storm event; this assumption is made if the times of obsevation of
     the maxima are at most 48 hours apart. The row names give the
     years of observation. There are 39 missing data values. There are
     only nine non-missing logical values.
