Objects have states and behaviors. Example: A dog has states - color, name, breed as well as behaviors – wagging the tail, barking, eating. An object is an instance of a class.
Class − A class can be defined as a template/blueprint that describes the behavior/state that the object of its type support.
Classes and Objects are used to to make your code more efficient and less repetitive by grouping similar tasks.
A class is used to define the actions and data structure used to build objects. The objects are then built using this predefined structure.
Pipe operators, available in
dplyr, and other R packages, process a data-object using a sequence of operations by passing the result of one step as input for the next step using infix-operators rather than the more typical R method of nested function calls.
Note that the intended aim of pipe operators is to increase human readability of written code. See Remarks section for performance considerations.
