Variables in R are containers for storing data values like numbers, text, or complex objects like vectors and data frames. R is dynamically typed — meaning you don’t have to declare the data type ahead of time.
📖 How to Declare Variables
Use <- or = for assignment (prefer <-)
Variable names are case-sensitive
No need to specify data type — R figures it out automatically
