dotPlot creates a dot plot. For data in groups the dotPlot is displayed stacked in one or not-stacked in different plot regions.

`x` |
vector with numeric values which should be plotted. |

`group` |
(optional) vector for grouping the values (see examples). |

`xlim` |
vector giving the lower and upper limit of the x-axis. |

`ylim` |
vector giving the lower and upper limit of the y-axis. |

`col` |
vector containing numeric values or strings for different colors for the groups in the dot plot. |

`xlab` |
a title for the x axis: |

`ylab` |
a title for the y axis: |

`pch` |
a vector of integers specifying symbols or a single character to be used for plotting points for the different groups in the dot plot. |

`cex` |
the amount by which points and symbols should be magnified relative to the default. |

`breaks` |
a vector giving the breakpoints for the binning of the values in x. |

`stacked` |
a logical vector specifying whether the single groups should be plotted in a stacked dot plot or in a single one.
By default |

`...` |
further graphical parameters (see |

.

values in x are assigned to the bins defined by breaks. The actual binning is done using hist.

`dotPlot`

a invisible matrix containing NA's and numeric values representing values in a bin. The number of bins is given by the number of columns of the matrix.
