Variables

Variables can be assigned using any of the leftward, rightward or equal to operator. You can print the variables using either print or cat functions.

How to declare variables

var-name = value
var-name <- value
value -> var-name

Naming convention of variables

Variable names can have only letters (both uppercase and lowercase letters), numbers, dot and underscore(_).
Variables naming cannot contain white spaces like first name which is a invalid variable name.
First letter of a variable should be either a letter or dot (.).
In R, Variable names are case sensitive and hence Name and name both are different.
It is always advisable to give some meaningful names to variables.

Example

var_logical <- FALSE  # Logical variable
  
var_numeric -> 797 # Numeric variable
  
var_integer = 53L  # integer variable
  
var_complex <- 5+2i  # complex variable
  
var_char<- "One Compiler"  # character variable
  
var_raw <- charToRaw("Hello World")  # raw variable
