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).
