anno_density {ComplexHeatmap}R Documentation

Using kernel density as annotation

Description

Using kernel density as annotation

Usage

anno_density(x, which = c("column", "row"), gp = gpar(fill = "#CCCCCC"),
    type = c("lines", "violin", "heatmap"), ...)

Arguments

x

a matrix or a list. If x is a matrix and if which is column, statistics for density is calculated by columns, if which is row, the calculation is by rows.

which

is the annotation a column annotation or a row annotation?

gp

graphic parameters. Note it is ignored if type equals to heatmap.

type

which type of graphics is used to represent density distribution.

...

pass to density

Value

A graphic function which can be set in HeatmapAnnotation constructor method.

Examples

mat = matrix(rnorm(32), nrow = 4)
f = anno_density(mat)
grid.newpage(); f(1:8)

f = anno_density(mat, which = "row", type = "violin")
grid.newpage(); f(1:4)

lt = lapply(1:4, function(i) rnorm(8))
f = anno_density(lt, type = "heatmap")
grid.newpage(); f(1:4)
