Calculate Sum, Mean, and Product of a Vector in R ignoring NA or NaN

R Programming: Vector Exercise-7 with Solution

Write a R program to find Sum, Mean and Product of a Vector, ignore element like NA or NaN.

Sample Solution :

R Programming Code :

# Create a numeric vector 'x' with elements 10, NULL, 20, 30, and NA
x = c(10, NULL, 20, 30, NA)

# Print a message indicating the calculation of the sum
print("Sum:")

# Calculate and print the sum of the elements in vector 'x', ignoring NA and NaN values
print(sum(x, na.rm=TRUE))

# Print a message indicating the calculation of the mean
print("Mean:")

# Calculate and print the mean of the elements in vector 'x', ignoring NA and NaN values
print(mean(x, na.rm=TRUE))  

# Print a message indicating the calculation of the product
print("Product:")

# Calculate and print the product of the elements in vector 'x', ignoring NA and NaN values
print(prod(x, na.rm=TRUE))

Output:

[1] "Sum:"
[1] 60
[1] "Mean:"
[1] 20
[1] "Product:"
[1] 6000                         

Explanation:

• x = c(10, NULL, 20, 30, NA): Creates a numeric vector x with elements 10, NULL (which is ignored), 20, 30, and NA (which represents a missing value).
• print("Sum:"): Prints the label "Sum:" to indicate that the following output will show the sum of the vector elements.
• print(sum(x, na.rm=TRUE)): Calculates and prints the sum of the elements in vector x, ignoring NA and NULL values, resulting in 60.
• print("Mean:"): Prints the label "Mean:" to indicate that the following output will show the mean of the vector elements.
• print(mean(x, na.rm=TRUE)): Calculates and prints the mean of the elements in vector x, ignoring NA and NULL values, resulting in 20.
• print("Product:"): Prints the label "Product:" to indicate that the following output will show the product of the vector elements.
• print(prod(x, na.rm=TRUE)): Calculates and prints the product of the elements in vector x, ignoring NA and NULL values, resulting in 6000.
