Integer type in R Programming - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to create an integer variable with value 10.

R Programming

x <- [1]

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

A"10"

B10L

C10.0

Das.character(10)

💡 Hint

Common Mistakes

Using quotes makes it a string, not an integer.

Using a decimal point makes it a numeric (double), not an integer.

In R, adding L after a number makes it an integer literal.

2fill in blank

medium

Complete the code to check if variable y is of integer type.

R Programming

is.integer([1])

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

A10

B"y"

Cas.integer(y)

Dy

💡 Hint

Common Mistakes

Passing the value 10 instead of the variable.

Passing the variable name as a string.

The function is.integer() checks the type of the variable passed to it.

3fill in blank

hard

Fix the error in the code to convert a numeric value to integer.

R Programming

z <- [1](5.7)

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

Aas.integer

Bas.character

Cas.numeric

Das.logical

Attempts:

💡 Hint

Common Mistakes

Using as.character() converts to string, not integer.

Using as.logical() converts to TRUE/FALSE, not integer.

Use as.integer() to convert numeric values to integers in R.

4fill in blank

hard

Fill both blanks to create a vector of integers from 1 to 5 and check its type.

R Programming

vec <- [1](1:5)
is_int <- [2](vec)

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

Aas.integer

Bis.integer

Cas.numeric

Dis.numeric

Attempts:

3 left

💡 Hint

Common Mistakes

Using as.numeric instead of as.integer.

Using is.numeric instead of is.integer.

as.integer() converts the sequence to integers, and is.integer() checks if the vector is integer type.

5fill in blank

hard

Fill all three blanks to create an integer vector, convert a number to integer, and check if it is integer.

R Programming

int_vec <- [1](c(2.5, 3.7, 4.1))
num <- [2](5.9)
check <- [3](num)

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

Aas.numeric

Bas.integer

Cis.integer

Dis.numeric

Attempts:

3 left

💡 Hint

Common Mistakes

Using as.numeric() instead of as.integer().

Using is.numeric() instead of is.integer().

Use as.integer() to convert values to integers and is.integer() to check the type.
