dotplot {broman} | R Documentation |

## Dot chart with a gray background

### Description

Like the `grayplot()`

function, but with one axis assumed to be categorical.

### Usage

```
dotplot(group, y, jiggle = NULL, max_jiggle = 0.45, rotate = FALSE, ...)
```

### Arguments

`group` |
Categorical coordinates for the plot |

`y` |
Coordinates of points in the plot |

`jiggle` |
Vector of amounts to jiggle the points horizontally,
or a character string ( |

`max_jiggle` |
Maximum jiggle value; passed to |

`rotate` |
If TRUE, have group as y-axis; default (FALSE) has group on x-axis. |

`...` |
Optional graphics arguments |

### Details

Calls `grayplot()`

with special choices of
graphics parameters for the case of categorical x.

If `group`

is a factor, the order of the groups is as in the
levels. Otherwise, we take `sort(unique(group))`

. So if you want to
control the order of the levels, make `group`

a factor with the levels
in the desired order, for example `group <- factor(group, levels=unique(group))`

.

### Value

None.

### Examples

```
x <- rnorm(40, c(1,3))
g <- rep(c("A", "B"), 20)
dotplot(g, x)
dotplot(g, x, "fixed")
dotplot(g, x, runif(length(g), -0.25, 0.25))
```
