Plot the multiples of a von Mises density distribution

## Usage

```
plot_density(
x,
kappa,
axial = TRUE,
n = 512,
norm_density = TRUE,
...,
scale = 1.1,
shrink = 1,
add = TRUE,
main = NULL,
labels = TRUE,
at = seq(0, 360 - 45, 45),
cborder = TRUE
)
```

## Arguments

- x
Data to be plotted. A numeric vector containing angles (in degrees).

- kappa
Concentration parameter for the von Mises distribution. Small kappa gives smooth density lines.

- axial
Logical. Whether data are uniaxial (

`axial=FALSE`

) or biaxial (`TRUE`

, the default).- n
the number of equally spaced points at which the density is to be estimated.

- norm_density
logical. Normalize the density?

- ...
Further graphical parameters may also be supplied as arguments.

- scale
radius of plotted circle. Default is

`1.1`

.- shrink
parameter that controls the size of the plotted function. Default is 1.

- add
logical. Add to existing plot? (

`TRUE`

by default).- main
Character string specifying the title of the plot.

- labels
Either a logical value indicating whether to plot labels next to the tick marks, or a vector of labels for the tick marks.

- at
Optional vector of angles at which tick marks should be plotted. Set

`at=numeric(0)`

to suppress tick marks.- cborder
logical. Border of rose plot.

## Examples

```
rose(san_andreas$azi, dots = TRUE, stack = TRUE, dot_cex = 0.5, dot_pch = 21)
plot_density(san_andreas$azi, kappa = 10, col = "seagreen", shrink = 1.5)
plot_density(san_andreas$azi, kappa = 10, col = "seagreen", add = FALSE, scale = .6)
