WebAug 5, 2016 · The idea behind the class function in R is to offer an object-oriented style of programming. Calling the class function on an R object returns all the classes that object is made of (i.e. its immediate class along with all the classes that immediate class inherits from). For instance, when you coerce a normal data.frame (a native R object) into a … WebIn R, we use the setClass () function to define a class. For example, Here, we have created a class named Student_Info with three slots (member variables): name, age, and GPA. Now to create an object, we use the new () function. For example, Here, inside new (), we have provided the name of the class "Student_Info" and value for all three slots. simple and sweet
