anno_text {ComplexHeatmap} | R Documentation

## Text Annotation

### Description

Text Annotation

### Usage

    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")
