id_l

<p>Trivial identity lens: returns and sets the object itself.</p>

datasets

Provides utilities to create and use lenses to simplify data
manipulation. Lenses are composable getter/setter pairs that provide a
functional approach to manipulating deeply nested data structures, e.g.,
elements within list columns in data frames. The implementation is based on
the earlier 'lenses' R package <https://github.com/cfhammill/lenses>,
which was inspired by the Haskell 'lens' package by Kmett (2012)
<https://github.com/ekmett/lens>, one of the most widely referenced
implementations of lenses. For additional background and history on the
theory of lenses, see the 'lens' package wiki:
