In R programming, variables are used to store and manipulate data. Variables can hold different data types like numeric, character, and logical values. The type of data stored determines the variable's data type. Variables allow values to be assigned and operations performed. In R, values are assigned to variables using the assignment operator "<-". Variable names should start with a letter and follow naming conventions like being descriptive and avoiding reserved words.

3. In R programming, variables are used to store and
manipulate data. A variable can be thought of as a named
container that holds a value. Variables provide a way to
refer to and work with data in your programs.
Variables in R can hold different types of data, such as
numeric values, character strings, logical values, and
more. The type of data stored in a variable determines its
data type. R is a dynamically typed language, which
means that the data type of a variable is inferred based
on the value assigned to it.
You can also update the value of a variable by
reassigning it using the assignment operator.

The print() function is then used to display the value of
the variable

They play a crucial role in programming as they allow us to store values and perform operations on them. In R,
we can assign values to variables using the assignment operator "<-". For example, x <- 10 assigns the
value 10 to the variable x, and y <- "Hello, World!" assigns the string "Hello, World!" to the variable
y.

5. Variable Naming Conventions
Discuss the rules and best practices for naming variables in R
When naming variables in R, it's important to follow certain rules and best practices. Here are
some guidelines:
•Variable names should start with a letter and can be followed by letters, digits, or periods.
•Avoid using reserved words or function names as variable names.
•Use descriptive names that convey the purpose or meaning of the variable.
•Variable names are case-sensitive, so age and Age are considered different variables.
