R Example for Beginners – R Program to create a vector and find the length and the dimension of the vector
In this Learn by Coding example, we are explaining how to write an R program to create a vector and find the length and the dimension of the vector. Here we are using a built-in function dim(),length() for this finding. The function dim() helps to retrieve or set the dimension of an object. And the function length() is used to get or set the length of vectors (including lists) and factors, and of any other R object. The syntax of these functions are

Two Machine Learning Fields
There are two sides to machine learning:
- Practical Machine Learning: This is about querying databases, cleaning data, writing scripts to transform data and gluing algorithm and libraries together and writing custom code to squeeze reliable answers from data to satisfy difficult and ill defined questions. It’s the mess of reality.
- Theoretical Machine Learning: This is about math and abstraction and idealized scenarios and limits and beauty and informing what is possible. It is a whole lot neater and cleaner and removed from the mess of reality.
