Selecting a Simple Random Sample

If you have a population of, say, 100 individuals with labels 1,...,100, then you can use the expression 1:100 to construct the sequence of labels. The command sample then creates a random sample. For a random sample of size 10 use

sample(1:100, 10)

Try it several times to see that you get a different sample each time. Also try using different population and sample sizes.
