The complete list of R Data types and structures

To make the best of the R language, you'll need a strong understanding of the basic data types and data structures and how to operate on those. Very Important to understand because these are the things you will manipulate on a day-to-day basis in R. Everything in R is an object.

The basic data types 

• logical (e.g., TRUE, FALSE)
• integer (e.g,, 2L, as.integer(3))
• numeric (real or decimal) (e.g, 2, 2.0, pi)
• complex (e.g, 1 + 0i, 1 + 4i)
• character (e.g, "a", "swc")

The basic data structures in R

• vector
• list
• matrix
• data frame
• factors
• tables

Vector in R

A vector is the most common and basic data structure in R and is pretty much the workhorse of R. 

Vectors can be of two types:

• atomic vectors
• lists
