anno_histogram: Histogram Annotation

In ComplexHeatmap: Make Complex Heatmaps

Description

Histogram Annotation

Usage

anno_histogram(x, which = c("column", "row"), n_breaks = 11,
    border = FALSE, 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?
n_breaks	Number of breaks for calculating histogram.
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(1000), nc = 10)
anno = anno_histogram(t(m), which = "row")
draw(anno, test = "row histogram")
anno = anno_histogram(t(m), which = "row", gp = gpar(fill = 1:10))
draw(anno, test = "row histogram with color")
anno = anno_histogram(t(m), which = "row", n_breaks = 20)
draw(anno, test = "row histogram with color")
