## Density Annotation

### Description

Density Annotation

### Usage

    anno_density(x, which = c("column", "row"),
        type = c("lines", "violin", "heatmap"), xlim = NULL,
        heatmap_colors = rev(brewer.pal(name = "RdYlBu", n = 11)),
        joyplot_scale = 1, border = TRUE, gp = gpar(fill = "#CCCCCC"),
        axis = TRUE, axis_param = default_axis_param(which),
        width = NULL, height = NULL)

### Arguments

`x` | A matrix or a list. If `x` is a matrix and if `which` is `column`, statistics for boxplots are calculated by columns, if `which` is `row`, the calculation is done by rows.
`which` | Whether it is a column annotation or a row annotation?
`type` | Type of graphics to represent density distribution. "lines" for normal density plot; "violine" for violin plot and "heatmap" for heatmap visualization of density distribution.
`xlim` | Range on x-axis.
`heatmap_colors` | A vector of colors for interpolating density values.
`joyplot_scale` | Relative height of density distribution. A value higher than 1 increases the height of the density distribution and the plot will represented as so-called "joyplot".
`border` | Wether draw borders of the annotation region?
`gp` | Graphic parameters for the boxes. The length of the graphic parameters should be one or the number of observations.
`axis` | Whether to add axis?
`axis_param` | parameters for controlling axis. See `default_axis_param` for all possible settings and default parameters.
`width` | Width of the annotation. The value should be an absolute unit. Width is not allowed to be set for column annotation.
`height` | Height of the annotation. The value should be an absolute unit. Height is not allowed to be set for row annotation.

### Value

An annotation function which can be used in `HeatmapAnnotation`.

### Examples

    m = matrix(rnorm(100), 10)
    anno = anno_density(m, which = "row")
    draw(anno, test = "normal density")
    anno = anno_density(m, which = "row", type = "violin")
    draw(anno, test = "violin")
    anno = anno_density(m, which = "row", type = "heatmap")
    draw(anno, test = "heatmap")
    anno = anno_density(m, which = "row", type = "heatmap",
        heatmap_colors = c("white", "orange"))
    draw(anno, test = "heatmap, colors")
