Simplify while loop in R

how do I simplify this while loop? It doesn't seem to work when I put != 2 && 3 && 12.

Thank you

while (sum(diceRoll) != 2 && sum(diceRoll) !=3 && sum(diceRoll) !=12)

Using the %in% operator, you could replace

while (sum(diceRoll) != 2 && sum(diceRoll) !=3 && sum(diceRoll) !=12)

by

while (!(sum(diceRoll) %in% c(2,3,12)))

The problem with your proposed solution is that 2 && 3 && 12 evaluates to TRUE so

while (sum(diceRoll) != 2 && 3 && 12)

parses as

while (sum(diceRoll) != TRUE)

which is functionally equivalent to

while (sum(diceRoll) != 1)

which is clearly not the intended meaning.
