Numbers
In the previous section, we saw 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:
numeric/double- representing real numbers;integer- for integer numbers;complex- for numbers with both a real and an imaginary part.
Yet, in our previous exercise, 10 was classified as a "double". To have R recognize it as an integer, appending L to the number is a straightforward method. For instance:
Differentiating between 10 and 10L is important because of how memory is utilized — integers take up less space.
Task
- Assign the current year's numerical value to a variable named
year, and ensure that it is of integer type by appendingL. - Determine and display the type of the variable
year.
Everything was clear?
