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).
