R Programming: Create Sequence, find Mean, and calculate Sum

R Programming: Basic Exercise-3 with Solution

Write a R program to create a sequence of numbers from 20 to 50 and find the mean of numbers from 20 to 60 and sum of numbers from 51 to 91.

Sample Solution :

R Programming Code :

# Print a message indicating that the sequence of numbers from 20 to 50 will be shown
print("Sequence of numbers from 20 to 50:")

# Generate and print a sequence of numbers from 20 to 50
print(seq(20,50))

# Print a message indicating that the mean of numbers from 20 to 60 will be shown
print("Mean of numbers from 20 to 60:")

# Calculate and print the mean of numbers from 20 to 60
print(mean(20:60))

# Print a message indicating that the sum of numbers from 51 to 91 will be shown
print("Sum of numbers from 51 to 91:")

# Calculate and print the sum of numbers from 51 to 91
print(sum(51:91))

Output:

[1] "Sequence of numbers from 20 to 50:"
 [1] 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44
[26] 45 46 47 48 49 50
[1] "Mean of numbers from 20 to 60:"
[1] 40
[1] "Sum of numbers from 51 to 91:"
[1] 2911                         

Explanation:

• print("Sequence of numbers from 20 to 50:")
  Prints a descriptive message indicating that the following output will be a sequence of numbers from 20 to 50.
• print(seq(20,50))
  Creates and prints a sequence of numbers starting from 20 and ending at 50 using the seq() function.
• print("Mean of numbers from 20 to 60:")
  Prints a message indicating that the next output will show the mean (average) of numbers from 20 to 60.
• print(mean(20:60))
  Calculates and prints the mean (average) of the numbers in the range from 20 to 60 using the mean() function.
• print("Sum of numbers from 51 to 91:")
  Prints a message indicating that the next output will show the sum of numbers from 51 to 91.
• print(sum(51:91))
  Calculates and prints the sum of all numbers from 51 to 91 using the sum() function.
