Basic data types in R data science

 

Basic data types in R

R works with numerous data types. Some of the most basic types to get started are:

• Decimal values like 4.5 are called numerics.
• Whole numbers like 4 are called integers. Integers are also numerics.
• Boolean values (TRUE or FALSE) are called logical.
• Text (or string) values are called characters.

Note how the quotation marks in the editor indicate that "some text" is a string.
