R tutorial and example for Beginners – R Program to sort a Data frame using order()
In this Learn by Coding example, we explain how to write an R program to sort a data frame using the order() function. Here we are using a built-in function order() for this sorting. The order() function helps to returns a permutation. It rearranges its first argument into ascending or descending order, breaking ties by further arguments. The syntax of order() is like

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.
