Read This question first then come back, because this is linked to the previous question

Oops, it seems like you are losing money. Time to rethink and adapt your strategy! This will require some deeper analysis...

After a short brainstorm in your hotel's jacuzzi, you realize that a possible explanation might be that your skills in roulette are not as well developed as your skills in poker. So maybe your total gains in poker are higher (or > ) than in roulette.

Instruction

  • Calculate total_poker and total_roulette as in the previous exercise. Use the sum() function twice.
  • Check if your total gains in poker are higher than for roulette by using a comparison. Simply print out the result of this comparison. What do you conclude, should you focus on roulette or on poker?

Program Code

# Poker and roulette winnings from Monday to Friday:
poker_vector <- c(140, -50, 20, -120, 240)
roulette_vector <- c(-24, -50, 100, -350, 10)
days_vector <- c("Monday", "Tuesday", "Wednesday", "Thursday", "Friday")
names(poker_vector) <- days_vector
names(roulette_vector) <- days_vector

# Calculate total gains for poker and roulette
total_poker <- sum(poker_vector)
total_roulette <- sum(roulette_vector)

# Check if you realized higher total gains in poker than in roulette 
total_poker > total_roulette

Output

> # Poker and roulette winnings from Monday to Friday:
> poker_vector <- c(140, -50, 20, -120, 240)
> roulette_vector <- c(-24, -50, 100, -350, 10)
> days_vector <- c("Monday", "Tuesday", "Wednesday", "Thursday", "Friday")
> names(poker_vector) <- days_vector
> names(roulette_vector) <- days_vector
> 
> # Calculate total gains for poker and roulette
> total_poker <- sum(poker_vector)
> total_roulette <- sum(roulette_vector)
> 
> # Check if you realized higher total gains in poker than in roulette 
> total_poker > total_roulette
[1] TRUE

Explanation

Hint
  • You partly calculated the answer to this question in the previous exercise already!
  • To check if 6 is larger than 5, you type 6 > 5. This returns a logical value (TRUE or FALSE).

How to learn from this program

First read the algorithm, then study the program code line by line. After that, compare the code with the output and finally go through the explanation. This approach helps learners understand both the logic and the implementation properly.

Quick Practice Flow

Use this small plan to get the best result from the program example.

  • Read the title and topic first
  • Understand the algorithm carefully
  • Study the code line by line
  • Check the output and compare the logic
