fish_encounters

Information about fish swimming down a river: each station represents an
autonomous monitor that records if a tagged fish was seen at that location.
Fish travel in one direction (migrating downstream). Information about
misses is just as important as hits, but is not directly recorded in this
form of the data.

datasets

Tools to help to create tidy data, where each
column is a variable, each row is an observation, and each cell
contains a single value.  'tidyr' contains tools for changing the
shape (pivoting) and hierarchy (nesting and 'unnesting') of a dataset,
turning deeply nested lists into rectangular data frames
('rectangling'), and extracting values out of string columns. It also
includes tools for working with missing values (both implicit and
explicit).
