Numbers
In the previous section, we observed that the number 10
was identified as a double
even though it is an integer. Let's delve into this peculiarity.
R can categorize numeric values into several types, which are:
double
- representing real numbers;integer
- for whole numbers;complex
- for numbers with both a real and an imaginary part.
To have R recognize 10
as an integer
instead of a double
, you can append L
to the number. Here’s how you can do it:
12typeof(10) # Example of double type typeof(10L) # Example of integer type
Differentiating between 10
and 10L
is important because of how memory is utilized — integers take up less space.

Assign the current year's numerical value to a variable named
year
, and ensure that it is ofinteger
type by appendingL
. -
Determine and display the type of the
year
variable:
