Program:

# 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)

# Assign days as names of poker_vector
names(poker_vector) <- c("Monday", "Tuesday", "Wednesday", "Thursday", "Friday")

# Assign days as names of roulette_vector
names(roulette_vector) <- c("Monday", "Tuesday", "Wednesday", "Thursday", "Friday")

# see poker_vector result
poker_vector
# see roulette_vector result
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)
> 
> # Assign days as names of poker_vector
> names(poker_vector) <- c("Monday", "Tuesday", "Wednesday", "Thursday", "Friday")
> 
> # Assign days as names of roulette_vector
> names(roulette_vector) <- c("Monday", "Tuesday", "Wednesday", "Thursday", "Friday")
> 
># see poker_vector result
> poker_vector
   Monday   Tuesday Wednesday  Thursday    Friday 
      140       -50        20      -120       240 
>
># see roulette_vector result
> roulette_vector
   Monday   Tuesday Wednesday  Thursday    Friday 
      -24       -50       100      -350        10
