sealevel2: Annual Sea Level Maxima at Dover and Harwich with Indicator
Description
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.source
