"cointoss" is a minimal R package that
provides functions to simulate tossing a coin.
coin()creates a coin object (of class"coin")toss()tosses a coin object, producing a"toss"object.plot()method for a"toss"object to plot frequencies of heads.summary()method for a"toss"object.
This package has been developed to illustrate some of the concepts behind the creation of an R package.
