Data Types in R Programming Language: Overview and Examples

In contrast to other programming languages like C and Java in R, the variables are not declared as some data type. The variables are assigned with R-Objects and the data type of the R-object becomes the data type of the variable. There are many types of R-objects. The frequently used ones are ?

• Vectors
• Lists
• Matrices
• Arrays
• Factors
• Data Frames

The simplest of these objects is the vector object and there are six data types of these atomic vectors, also termed as six classes of vectors. The other R-Objects are built upon the atomic vectors.
