These utilities facilitate the programmatic manipulations of
formulas, expressions, calls, names, symbols and other objects.

These utilities facilitate the programmatic manipulations of
formulas, expressions, calls, names, symbols and other objects. These
objects all share the same structure: a left-hand side operator and
right-hand side. This packages provides methods for accessing and modifying
the structures as well as extracting names and symbols from these objects.

Programmatic Utilities for Manipulating Formulas, Expressions,
Calls, Assignments and Other R Objects
These utilities facilitate the programmatic manipulations of
formulas, expressions, calls, assignments and other R language objects.
These objects all share the same structure: a left-hand side, operator and
right-hand side. This packages provides methods for accessing and
modifying this structures as well as extracting and replacing names and
symbols from these objects.
