Introduction and Overview

Hello! Today's lesson is about Data Binning in R. This process involves grouping numerous continuous data values into a smaller number of categories or "bins." For instance, ages can be binned into categories like "Child," "Teen," and "Adult." We'll utilize R's built-in functions, particularly the cut function, for data binning. Ready to explore? Let's get started!

Binning is a widely utilized data simplification technique. It facilitates interpretation by mitigating the complexities of continuous values. For example, grouping student grades into categories such as "A," "B," "C," "D," "F" better highlights performance patterns than do individual scores.

Basic Binning in R

R provides cut, a function to perform binning. To group ages into categories such as "Young," "Middle-aged," and "Old," for example, we use:

The cut function in R determines the break points based on the breaks argument. If breaks is specified as a single number, the range of the data is divided into that number of equal-width intervals. For example, breaks = 4 splits the data into four intervals with equal widths.

In the provided example, the function classifies the range of into three bins, as .
