calculate_area_of_rectangle that takes two parameters, length and width, representing the dimensions of a rectangle. The function should calculate and return the area of the rectangle using the formula area = length * width.Test your function with different 2 sets of values and print the results.
calculate_area_of_rectangle <- function(length, width) {
area <- length * width
return(area)
}
# Test with two sets of values
result1 <- calculate_area_of_rectangle(5, 3)
result2 <- calculate_area_of_rectangle(10, 4)
print(result1)[1] 15print(result2)[1] 40calculate_average that accepts a vector of numeric values as its parameter. The function should calculate the average of the provided values and return the result. Ensure that the function handles the case when an empty vector is passed, and in such cases, it should print a message indicating that the vector is empty. (hint: use if/else)calculate_average <- function(values) {
if (length(values) == 0) {
print("The vector is empty.")
} else {
average <- mean(values)
return(average)
}
}
# Test with a vector of numbers
print(calculate_average(c(10, 20, 30, 40)))[1] 25# Test with an empty vector
calculate_average(numeric(0))[1] "The vector is empty."check_even_odd that takes an integer as its parameter. The function should determine whether the provided integer is even or odd and print a corresponding message. Test your function on the following values: 14, and 27.check_even_odd <- function(number) {
if (number %% 2 == 0) {
print("The number is even.")
} else {
print("The number is odd.")
}
}
# Test the function
check_even_odd(14)[1] "The number is even."check_even_odd(27)[1] "The number is odd."Output the date you answered this homework using a function.
Sys.Date()[1] "2026-10-08"Use the airquality dataset and perform the following: 1. Check the structure of the dataset. 2. Check the summary. 3. Check the NA’s.
