Adds a layers of texts above the heatmap tiles to a `InputHeatmap`, that on evaluation creates a `ComplexHeatmap`

layer_text() from a `InputHeatmap` object, adds a text annotation layer.

layer_text(.data, ..., .value, .size = NULL)

# S4 method for InputHeatmap
layer_text(.data, ..., .value, .size = NULL)

Arguments

.data

A `InputHeatmap`

...

Expressions that return a logical value, and are defined in terms of the variables in .data. If multiple expressions are included, they are combined with the & operator. Only rows for which all conditions evaluate to TRUE are kept.

.value

A column name or character string.

.size

A column name or a double. The size of the elements of the layer.

Value

A `InputHeatmap` object that gets evaluated to a `ComplexHeatmap`

A `InputHeatmap` object that gets evaluated to a `ComplexHeatmap`

Details

It uses `ComplexHeatmap` as visualisation tool.
