dotchart {graphics} | R Documentation |

Draw a Cleveland dot plot.

dotchart(x, labels = NULL, groups = NULL, gdata = NULL, cex = par("cex"), pch = 21, gpch = 21, bg = par("bg"), color = par("fg"), gcolor = par("fg"), lcolor = "gray", xlim = range(x[is.finite(x)]), main = NULL, xlab = NULL, ylab = NULL, ...)

`x` |
either a vector or matrix of numeric values (`NA` s are
allowed). If `x` is a matrix the overall plot consists of
juxtaposed dotplots for each row. |

`labels` |
a vector of labels for each point.
For vectors the default is to use `names(x)` and for matrices
the row labels `dimnames(x)[[1]]` . |

`groups` |
an optional factor indicating how the elements of
`x` are grouped.
If `x` is a matrix, `groups` will default to the columns
of `x` . |

`gdata` |
data values for the groups. This is typically a summary such as the median or mean of each group. |

`cex` |
the character size to be used. Setting `cex`
to a value smaller than one can be a useful way of avoiding label
overlap. Unlike many other graphics functions, this sets the actual
size, not a multiple of `par("cex")` . |

`pch` |
the plotting character or symbol to be used. |

`gpch` |
the plotting character or symbol to be used for group values. |

`bg` |
the background color of plotting characters or symbols to be
used; use `par(bg= *)` to set the background color of
the whole plot. |

`color` |
the color(s) to be used for points and labels. |

`gcolor` |
the single color to be used for group labels and values. |

`lcolor` |
the color(s) to be used for the horizontal lines. |

`xlim` |
horizontal range for the plot, see
`plot.window` , e.g. |

`main` |
overall title for the plot, see `title` . |

`xlab, ylab` |
axis annotations as in `title` . |

`...` |
graphical parameters can also be specified as arguments. |

This function is invoked for its side effect, which is to produce two
variants of dotplots as described in Cleveland (1985).

Dot plots are a reasonable substitute for bar plots.
