Description

Draw the heatmap annotations

Usage

## S4 method for signature 'HeatmapAnnotation'
draw(object, index, k = NULL, n = NULL, align_to = "bottom", ...)

Arguments

object	a HeatmapAnnotation-class object.
index	a vector of order.
k	if row annotation is splitted, the value identifies which row slice.
n	total number of row slices.
align_to	if the allocated space is more than than the column annotation itself, should the viewport be aligned to the top or bottom?
...	pass to viewport which contains all annotations.

Examples

df = data.frame(type = c("a", "a", "a", "b", "b", "b"))
ha = HeatmapAnnotation(df = df)
grid.newpage(); draw(ha, 1:6)
grid.newpage(); draw(ha, 6:1)

ha = HeatmapAnnotation(df = df, col = list(type = c("a" =  "red", "b" = "blue")))
grid.newpage(); draw(ha, 1:6)

ha = HeatmapAnnotation(df = df, col = list(type = c("a" =  "red", "b" = "blue")), 
    which = "row")
grid.newpage(); draw(ha, 1:6)

ha = HeatmapAnnotation(points = anno_points(1:6))
grid.newpage(); draw(ha, 1:6)

ha = HeatmapAnnotation(histogram = anno_barplot(1:6))
grid.newpage(); draw(ha, 1:6)

mat = matrix(rnorm(36), 6)
ha = HeatmapAnnotation(boxplot = anno_boxplot(mat))
grid.newpage(); draw(ha, 1:6)
