I have been trying to use the rbeta() function to generate random beta
variates with a particular mean and standard deviaiton  for some simulation
I am working on, however I am unsure of the relationship between the
parameters shape1 and shape2 and the mean and standard deviation of the
distribution. I am guessing that there is a formula for this, but I am
unsure what it is. Can anyone advise me?
