Types in R

Step 1 of 8

Basic Types

Like many other languages, R has a variety of basic types and more complex types that can be created from the 'atomic' ones. Basic types in R are:

  • numeric (real)
  • integer
  • character
  • logical
  • complex

Creating a variable of a specific type can be done by using assign <- operator:

num <- 10

For initialising text variable you can use both ' and ":

chr <- "some text"

Logical values can be created using TRUE/FALSE or just T/F:

log <- TRUE

Notice that R is dynamic when it comes to types, so you can assign character value to the variable that previously was set to different type:

myVar <- 10

myVar <- 'text value'
