Barplot Annotation

Barplot Annotation

anno_barplot(x, baseline = 0, which = c("column", "row"), border = TRUE, bar_width = 0.6,
    gp = gpar(fill = "#CCCCCC"), ylim = NULL, extend = 0.05, axis = TRUE,
    axis_param = default_axis_param(which),
    width = NULL, height = NULL, ...)

Arguments

x	The value vector. The value can be a vector or a matrix. The length of the vector or the number of rows of the matrix is taken as the number of the observations of the annotation. If x is a vector, the barplots will be represented as stacked barplots.
baseline	baseline of bars. The value should be "min" or "max", or a numeric value. It is enforced to be zero for stacked barplots.
which	Whether it is a column annotation or a row annotation?
border	Wether draw borders of the annotation region?
bar_width	Relative width of the bars. The value should be smaller than one.
gp	Graphic parameters for points. The length of each graphic parameter can be 1, length of x if x is a vector, or number of columns of x is x is a matrix.
ylim	Data ranges. By default it is range(x) if x is a vector, or range(rowSums(x)) if x is a matrix.
extend	The extension to both side of ylim. The value is a percent value corresponding to ylim[2] - ylim[1].
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.
...	Other arguments.

Value

An annotation function which can be used in HeatmapAnnotation.

Examples

anno = anno_barplot(1:10)
draw(anno, test = "a vector")

m = matrix(runif(4*10), nc = 4)
m = t(apply(m, 1, function(x) x/sum(x)))
anno = anno_barplot(m, gp = gpar(fill = 2:5), bar_width = 1, height = unit(6, "cm"))
draw(anno, test = "proportion matrix")
