Draws a simple random sampling without replacement of size n (equal probabilities, fixed sample size, without replacement).
selected only: show the table with selected observations only.
all observations with remark: show the table with all observations and a remark field.
fixed schedule: use a fixed seed in R to generate the same simulation results.
random schedule: use a random seed in R to generate the different simulation results.
