Hello All,
A colleague of mine started working with R and out of curiosity I did
some research on the language. Very nice. In my opinion this is one
of the best languages I've found for getting tasks I'm interested in
done. I wrote this simple die roller and was curious to know if it is
R enough.

# Input:
# die_size - 4, 6, 8, 10, 20
# number_of_dice - How many dice to roll
# number_of_rolls - How many times to roll the dice
#
# Output:
# rolls - The array holding the values of the dice
#
##############################################################################

function(die_size, number_of_dice, number_of_rolls)
{
rolls <- array(0, dim=c(number_of_rolls, number_of_dice))
for (i in 1:number_of_rolls)
{
rolls[i,] <- sample(die_size, number_of_dice, replace=TRUE)
}
return(rolls)
}
Any thoughts on this function? Is there a better way of doing it in
R? Can you tell I used to play AD&D?
Thanks,
Joe
