Data Types
Understanding data types is fundamental in R programming as they dictate how data is stored, interpreted, and manipulated, so let's explore the various data types in R and their characteristics.

Each data type serves specific purposes and ensures that the data is handled appropriately according to its nature.
Here are the most common data types in R:
Type | Description |
---|---|
double |
Represents real numbers (double-precision floating-point). |
integer |
Represents whole numbers. |
character |
Represents text strings. |
logical |
Represents Boolean values (TRUE or FALSE ). |
To determine the data type of a given variable, you would use the typeof()
function, providing the respective variable name as its argument. For example:
Take the initiative to practice this function on your own!
Task
- Assign the number
10
to a variable namedchapter
. - Display the data type of the
chapter
variable.
