01 Nuts and Bolts - Assignment

Write R code to generate the expected output shown below each question.

1. Create two variables ‘x’ and ‘y’ and assign values 3 and 6. Print the value of x+y

## [1] 9

2. Create a variable named ‘welcome’ and assign the text “Welcome to R!” to it. Print the variable.

## [1] "Welcome to R!"

3. Create a vector named ‘rainfall’ with numbers 16, 18, 14, 22, 27, 17, 19, 17, 17, 22, 20, and 22. Print the vector.

##  [1] 16 18 14 22 27 17 19 17 17 22 20 22

4. Calculate the mean rainfall

## [1] 19.25

5. Values in the vector ‘rainfall’ are in inches. You can calculate the rainfall in centimeters by dividing each value by 0.3937. Write a ‘for’ loop to iterate over each value in the rainfall vector and print the rainfall in centimeters

## [1] 40.64
## [1] 45.72
## [1] 35.56
## [1] 55.88
## [1] 68.58
## [1] 43.18
## [1] 48.26
## [1] 43.18
## [1] 43.18
## [1] 55.88
## [1] 50.8
## [1] 55.88

6. Use a ‘for’ loop and an ‘if-else’ condition to print the values only if the rainfall is greater than 50 centimerters.

## [1] 55.88
## [1] 68.58
## [1] 55.88
## [1] 50.8
## [1] 55.88

7. Create a function to covert rainfall in inches to centimeters. Round the answer to 2 decimal places. Pass the value 24 to the function and print the output with “cm” at the end.

## [1] "60.96 cm"
