Density Annotation

anno_density(x, which = c("column", "row"),
    type = c("lines", "violin", "heatmap"),
    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)

`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.
`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.

An annotation function which can be used in HeatmapAnnotation.
