Variables:

• #Variables in R serve as containers to store values. R primarily utilizes five main variable types: Integer, Double, Complex, Character, and Logical.

• In R, the assignment operator “<-” is used to assign a value to a variable.

• integer(non-decimal numbers) , we use L with the value.
  • a<- 2L
  • typeof( a) # to check the type of datatype is the value assigned

• Double(decimal number) , by default R uses this. 
  • b <- 2.5
  • typeof ( b)

• Complex
  • c <- 2+3i
  • typeof( c)

• Character( for strings/ letters), always use quotes to write strings                                
  • d <- “Hi”
  • typeof (d)

• Logical : TRUE or FALSE or use T or F            
  • e <- TRUE
  • typeof(e)

• Next, ensure to save your R script to prevent any loss of work. To create a new script for additional coding, click on the “+” button located at the top left corner of R Studio and select “R Script.”

• To reset and clear the environment, click on the broom button located in the Environment section. This action allows you to start with a fresh workspace.

To execute the code in R Studio

• In contrast to other programming languages where commands like “Print” or “printf” are used to execute the program.
• In R, executing the program is as simple as calling the object in the next line of code.

Eg : Var1 <- 5                  

Var2 <- 10

Var <- Var1 + Var2

Var     # to execute the code
