Practice - 5 Tasks

1fill in blank

easy

Complete the code to assign the value 10 to the variable x.

R Programming

x [1] 10

Drag options to blanks, or click blank then click option'

B->

C<-

D==

Attempts:

3 left

💡 Hint

Common Mistakes

Using '==' which is a comparison operator, not assignment.

Using '->' which assigns in the opposite direction.

In R, the most common assignment operator is <-, which assigns the value on the right to the variable on the left.

2fill in blank

medium

Complete the code to assign the value 5 to the variable y using the rightward assignment operator.

R Programming

5 [1] y

Drag options to blanks, or click blank then click option'

B->

C=

D==

💡 Hint

Common Mistakes

Using '<-' which assigns leftward.

Using '==' which is for comparison.

The rightward assignment operator -> assigns the value on the left to the variable on the right.

3fill in blank

hard

Fix the error in the code to correctly assign 20 to variable z.

R Programming

z [1] 20

Drag options to blanks, or click blank then click option'

A<-

B==

C->

D=

Attempts:

3 left

💡 Hint

Common Mistakes

Using '==' instead of an assignment operator.

Using '=' which is valid but less common in R for assignment.

The operator <- correctly assigns the value 20 to variable z. The operator == is for comparison, not assignment.

4fill in blank

hard

Fill both blanks to assign the value 15 to variable a using the standard assignment operator and then print a.

R Programming

a [1] 15
print([2])

Drag options to blanks, or click blank then click option'

A<-

Ba

Cprint

D->

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'print' as the assignment operator.

Printing the wrong variable.

Use <- to assign 15 to a. Then print the value of a by passing it to the print() function.

5fill in blank

hard

Fill all three blanks to assign 30 to variable b, then assign b's value to c, and finally print c.

R Programming

b [1] 30
c [2] b
print([3])

Drag options to blanks, or click blank then click option'

A<-

B->

Cc

Db

💡 Hint

Common Mistakes

Using the rightward assignment operator incorrectly.

Printing the wrong variable.

Use <- to assign 30 to b, then assign b to c. Finally, print c to see the value.
