Hi Dennis,
I see your point about using a different name for the runif() functions,
other then the one I used to stimulate the bias coins. I start to get what
you and David meant after thinking it through for a while regarding with
comparison the biased dice and the uniform distribution, but the

Hi Josh,
I think I know where does the 50+ warning is coming from,
because I used n in runif(n), similarly I get 50+ warnings if I use
runif(1000). Yet if I use runif(1) the warnings() doesn't show.

Dear Philip,
Trying to use 5 nested ifelse() statements will not be the same as a
series of if statements, and will also be quite messy.
Also, consider these lines of your code:
x <- sample(1:6,n,replace=TRUE,prob=c(1,1,2,3,2,1)/10)
x = runif(n)
First you assign n samples of 1:6 to 'x', then yo
Hi Philip,
Why do you want to use ifelse? It is not an alternative to an if then
else structure, but a way of iterating over a vector with a statement,
returning one value it is true, another if false. An example:
x = runif(100)
y = ifelse(x > 0.5, "Larger", "Smaller")
x
y
cheers,

hello people,
I want to make a biased dice using the sample() function and print out the
results after n number of runs, I've successfully generated the dice using
the following command:

for(i in 1:n){
x<-sample(1:6,n,replace=TRUE,prob=c(1,1,2,3,2,1)/10)
x=runi
