What is a factor variable, and why would you use one?..

Answer / Ashok Kumar

A factor variable is a type of discrete data in R, which allows categorical data to be stored and manipulated. You would use it when your data consists of categories or labels instead of numerical values. It helps in data analysis and modeling, especially for statistical tests that require nominal or ordinal data.
