plots (part of) outer and inner circle and colors inbetween; color can be a palette.

1 2 |

`r1 ` |
radius of outer circle. |

`r2 ` |
radius of inner circle. |

`mid ` |
midpoint of circle. |

`dr ` |
size of segments, in radians, to draw circle (decrease for smoother). |

`from ` |
starting angle for circle segment, radians. |

`to ` |
final angle for circle segment, radians. The segment is drawn counterclockwise. The default is to draw a full circle. |

`col ` |
color palette to be used; also allowed are two extremes or one value. |

`values ` |
if not |

`zlim ` |
Only if |

`lwd ` |
width of external line. |

`lcol ` |
line color. |

`... ` |
arguments passed to R-function polygon. |
