What are R arithmetic operators?
a) Operators that perform basic arithmetic operations like addition, subtraction, multiplication, division, and exponentiation
b) Operators that compare values
c) Operators that combine logical expressions
d) Operators that assign values to variables
Answer:
a) Operators that perform basic arithmetic operations like addition, subtraction, multiplication, division, and exponentiation
Explanation:
R arithmetic operators are used to perform basic mathematical operations on numerical data. These operators include:
- Addition (+): Adds two values.
- Subtraction (-): Subtracts the second value from the first.
- Multiplication (*): Multiplies two values.
- Division (/): Divides the first value by the second.
- Exponentiation (^): Raises the first value to the power of the second.
# Examples of R arithmetic operators
a <- 10 + 5 # Addition
b <- 10 - 5 # Subtraction
c <- 10 * 5 # Multiplication
d <- 10 / 5 # Division
e <- 10 ^ 2 # Exponentiation
print(a) # Output: 15
print(b) # Output: 5
print(c) # Output: 50
print(d) # Output: 2
print(e) # Output: 100In this example, arithmetic operations are performed on numeric values, and the results are stored in variables. These operators are fundamental to performing calculations and data analysis in R.
Arithmetic operators in R are straightforward and intuitive, allowing you to perform a wide range of mathematical computations on data sets with ease.
