After one week in Las Vegas and still zero Ferraris in your garage, you decide that it is time to start using your data analytical superpowers.

Before doing a first analysis, you decide to first collect all the winnings and losses for the last week:

For poker_vector:

On Monday you won $140
Tuesday you lost $50
Wednesday you won $20
Thursday you lost $120
Friday you won $240

For roulette_vector:

On Monday you lost $24
Tuesday you lost $50
Wednesday you won $100
Thursday you lost $350
Friday you won $10

You only played poker and roulette, since there was a delegation of mediums that occupied the craps tables. To be able to use this data in R, you decide to create the variables poker_vector and roulette_vector.

Program Code

# Poker winnings from Monday to Friday
poker_vector <- c(140, -50, 20, -120, 240)

# Roulette winnings from Monday to Friday
roulette_vector <-  c(-24, -50, 100, -350, 10)

poker_vector
roulette_vector

Output

> # Poker winnings from Monday to Friday
> poker_vector <- c(140, -50, 20, -120, 240)
> 
> # Roulette winnings from Monday to Friday
> roulette_vector <-  c(-24, -50, 100, -350, 10)
> 
> poker_vector
[1]  140  -50   20 -120  240
> roulette_vector
[1]  -24  -50  100 -350   10

Explanation

Assign the winnings/losses for roulette to the variable roulette_vector.

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.

Practice suggestion

After understanding this example, try to rewrite the same program without looking at the code. Then change some values or logic and run it again. This helps improve confidence and keeps learners engaged on the page for longer.
