You need to know the exact distribution of the random numbers you want 
to generate. For rnorm, in fact, you do not just specify the mean and 
the variance, but implicitely also that the data is normally 
distributed. Likewise, it is not sufficient to give min, max, skewness 
etc, you also need to know the distribution and then maybe you can use 
runif() as base for your code.
