Hi, I’m Zubair Goraya, a data scientist with over 5 years of experience. I’ve encountered many challenges with creating new variables in R during my PhD research, and I’m here to share the solutions I discovered.
What are the variables in R?
In R language, variables are defined as objects that can store values. These values range from single values to complex data frames.
Why do we create new variables using R?
- Data Manipulation and Transformation
- Calculations and Comparisons
- Function and Conditional Logic
- Feature Engineering
- Data Merging
