How do you declare a variable in R?

In R, you declare a variable using the assignment operator <- or =. The left-hand side of the operator is the variable name, and the right-hand side is the value to be assigned to the variable.

# Declaring variables in R
x <- 10      # Using the <- operator
y = 20       # Using the = operator
z <- x + y   # Assigning the result of an expression

print(x)  # Output: 10
print(y)  # Output: 20
print(z)  # Output: 30

In this example, the variables x, y, and z are declared and assigned values using both <- and = operators. The <- operator is more commonly used in R.

Variables in R are dynamically typed, meaning their types are inferred from the values assigned to them. This flexibility allows you to easily manage and manipulate different types of data within your R programs.
