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, ...)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 |
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 |
ylim |
Data ranges. By default it is |
extend |
The extension to both side of |
axis |
Whether to add axis? |
axis_param |
parameters for controlling axis. See |
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. |
An annotation function which can be used in HeatmapAnnotation.
