R Program to implement if else statement

How to implement the if-else statement

Here we are explaining how to write an R program to implement the if-else statement. Here we are using a control statement if-else for checking. The if-else statement helps to check the condition based on the condition the expression is performed. The syntax of if-else statement is like,

if (condition1) { expr1 } else if (condition2) { expr2 } else if (condition3) { expr3 } else { expr4 }

How to implement the if-else statement in the R program

Below are the steps used in the R program to implement the if-else statement. In this R program, we first create a vector quantity and assign it with a value of 50. Check the value of quantity using if-else the statement. Based on the condition print the corresponding statement.

ALGORITHM

• STEP 1: Assign variable quantity with vector value 50
• STEP 2: Check the value of quantity using if statement as if (quantity > 40)
• STEP 3: Give the print statement inside if the condition
• STEP 4: Give the print statement inside else the condition
• STEP 5: print the statement based on the true condition

R Source Code

# Create vector quantity

quantity <-  50

# Set the is-else statement
if (quantity > 40) {
  
    print('Great you sold a lot!')
  
} else {
  
    print('Not enough for today')  
  
}

R Source Code

# Create vector quantity

quantity <-  50

# Set the is-else statement
if (quantity > 60) {
  
    print('Great you sold a lot!')
  
} else {
  
    print('Not enough for today')  
  
}
