This function provides a simulation to the process of flipping coins and computes the frequencies for ‘heads’ and ‘tails’.

`faces` |
an integer or a character vector. See details below. |

`prob` |
the probability vector of showing each face. If |

`border` |
The border style for the rectangles which stand for probabilities. |

`grid` |
the color for horizontal grid lines in these rectangles |

`col` |
The colors to annotate different faces of the ‘coin’. |

`type, pch, bg` |
See |

`digits` |
integer indicating the precision to be used in the annotation of frequencies in the plot |

If `faces`

is a single integer, say 2, a sequence of integers from 1 to
`faces`

will be used to denote the faces of a coin; otherwise this
character vector just gives the names of each face.

When the *i*-th face shows up, a colored thin rectangle will be added to
the corresponding place (the *i*-th bar), and there will be corresponding
annotations for the number of tosses and frequencies.

The special argument `grid`

is for consideration of a too large number
of flipping, in which case if you still draw horizontal lines in these
rectangles, the rectangles will be completely covered by these lines, thus we
should specify it as `NA`

.

At last the frequency for each face will be computed and shown in the header
of the plot – this shall be close to `prob`

if
`ani.options('nmax')`

is large enough.

A list containing

`freq` |
A vector of frequencies (simulated probabilities) |

`nmax` |
the total number of tosses |

You may change the colors of each face using the argument `col`

(repeated if shorter than the number of faces).
