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

Source: R/methods.R

layer_arrow_up() from a `InputHeatmap` object, adds a bar annotation layer.

layer_arrow_up(.data, ..., .size = NULL)

# S4 method for class 'InputHeatmap'
layer_arrow_up(.data, ..., .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.

.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

maturing

It uses `ComplexHeatmap` as visualisation tool.
