\title{Demonstration for simple random sampling without replacement}
\usage{
sample.simple(
  nrow = 10,
  ncol = 10,
  size = 15,
  p.col = c("blue", "red"),
  p.cex = c(1, 3)
)
}
\arguments{
\item{nrow}{the desired number of rows of the sample frame.}

\item{ncol}{the desired number of columns of the sample frame.}

\item{size}{the sample size.}

\item{p.col, p.cex}{different colors /magnification rate to annotate the
population and the sample}
}
\value{
None (invisible \code{NULL}).
}
\description{
The whole sample frame is denoted by a matrix (\code{nrow * ncol}) in the
plane just for convenience, and the points being sampled are marked out (by
red circles by default). Each member of the population has an equal and known
chance of being selected.
