Text Annotation

Text Annotation

anno_text(x, which = c("column", "row"), gp = gpar(),
    rot = guess_rot(), just = guess_just(),
    offset = guess_location(), location = guess_location(),
    width = NULL, height = NULL)

Arguments

x	A vector of text.
which	Whether it is a column annotation or a row annotation?
gp	Graphic parameters.
rot	Rotation of the text, pass to grid.text.
just	Justification of text, pass to grid.text.
offset	Depracated, use location instead.
location	Position of the text. By default rot, just and location are automatically inferred according to whether it is a row annotation or column annotation. The value of location should be a unit object, normally in npc unit. E.g. unit(0, 'npc') means the most left of the annotation region and unit(1, 'npc') means the most right of the annotation region.
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

anno = anno_text(month.name)
draw(anno, test = "month names")
anno = anno_text(month.name, gp = gpar(fontsize = 16))
draw(anno, test = "month names with fontsize")
anno = anno_text(month.name, gp = gpar(fontsize = 1:12+4))
draw(anno, test = "month names with changing fontsize")
anno = anno_text(month.name, which = "row")
draw(anno, test = "month names on rows")
anno = anno_text(month.name, location = 0, rot = 45,
    just = "left", gp = gpar(col = 1:12))
draw(anno, test = "with rotations")
anno = anno_text(month.name, location = 1,
    rot = 45, just = "right", gp = gpar(fontsize = 1:12+4))
draw(anno, test = "with rotations")
