Demonstration for the cluster sampling

Description

Each rectangle stands for a cluster, and the simple random sampling without replacement is performed for each cluster. All points in the clusters being sampled will be drawn out.

Usage

sample.cluster(
  pop = ceiling(10 * runif(10, 0.2, 1)),
  size = 3,
  p.col = c("blue", "red"),
  p.cex = c(1, 3),
  ...
)

Arguments

pop	a vector for the size of each cluster in the population.
size	the number of clusters to be drawn out.
p.col, p.cex	different colors / magnification rate to annotate the population and the sample
...	other arguments passed to rect to annotate the “clusters”

Value

None (invisible NULL).
