Practice - 5 Tasks

1fill in blank

easy

💡 Hint

Common Mistakes

Using '==' which is for comparison, not assignment.

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

In R, the common way to assign a value to a variable is using the left arrow operator <-.

2fill in blank

medium

Complete the code to assign the value 5 to the variable y using the equals sign.

R Programming

y [1] 5

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

💡 Hint

Common Mistakes

Using '==' which is for comparison, not assignment.

Using '<-' which is also correct but not the answer here.

In R, you can also assign values using the equals sign =.

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:

💡 Hint

Common Mistakes

Using '==' instead of an assignment operator.

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

The operator <- correctly assigns the value 20 to variable z. The operator == is for comparison and causes an error here.

4fill in blank

hard

Fill both blanks to assign 15 to a and 25 to b using the correct operators.

R Programming

a [1] 15
b [2] 25

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

A<-

B=

C==

D->

Attempts:

3 left

💡 Hint

Common Mistakes

Using '==' which is for comparison.

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

Both <- and = can be used for assignment in R. Here, <- assigns 15 to a, and = assigns 25 to b.

5fill in blank

hard

Fill all three blanks to assign values 100, 200, and 300 to variables x, y, and z respectively using correct assignment operators.

R Programming

x [1] 100
y [2] 200
z [3] 300

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

A<-

B=

C->

D==

Attempts:

3 left

💡 Hint

Common Mistakes

Using '==' instead of assignment.

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

Use <- or = for assignment. Here, <- assigns to x and z, and = assigns to y. The operator -> assigns in the opposite direction, and == is for comparison.
