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.

try out some of the assignments posted in the university forum hoping to get

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:
mydie2<-function(n=1000,y=NULL,...){
for(i in 1:n){
x<-sample(1:6,n,replace=TRUE,prob=c(1,1,2,3,2,1)/10)
x=runi
what command to use to standardize my data to mean = 0, and SD=1.
the data I want to standardize/centroid is in column format.
So I'm thinking of using:
col.mean.stdised=apply(data.df,2,function(z){z-mean(z)})
but, what command should I use to put my SD =1?
Thanks!
