kwichmann / die_roll_simulator.R
Created September 16, 2016 08:55
Simulates rolling two dice pools against each other. Most sixes win, if tied, most fives win, if tied most fours win ... and so on.
roll <- function(n)
sample(1:6, n, replace = T)
number_of <- function(roll, n)
sum(roll == n)
win <- function(roll1, roll2) {
for (n in 6:1) {
if (number_of(roll1, n) > number_of(roll2, n)) return(1)
if (number_of(roll1, n) < number_of(roll2, n)) return(2)
