... Probably need to distinguish "whole object approach" from "object
oriented" approach. They are different and almost orthogonal in R. R
tutorials discuss such matters, and there are many good ones on the
Web, including the "Intro to R" tutorial that ships with R. The OP
should spend some time with one or more to learn more about this. This
list cannot provide such extended explanation.

> The reason for taking an object oriented approach using vectorized code, is that frequently, the R code that you write is internally calling compiled C code to perform the actual iterations over the object structure. Thus, being that compiled C code is much faster than interpreted R code, there is significant efficiency to be achieved by taking an object oriented approach to key operations.
