How the dynamics of a sports simulation game works?

I would like to create a baseball simulation game. Are these sports management games based on luck? A management game entirely based on luck is not fair, but it cannot be too predictable either. How does the logic behind these games work?

In R, how to generate a dataset consisting of the means of all column of a dataframe?

I can generate 20 observations of a uniform distribution with the runif function : runif(n=20) and 100 replicates of the same distribution as following. df <- replicate( 100, runif(n=20)) This creates df a matrix of dimensions [20,100] which I can…
