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. 

In addition, when used, a single line of vectorized code and/or a vectorized function can replace multiple lines of code in a different language. Thus, from a coding efficiency and readability standpoint, it is far more efficient.
