In stemangiola/tidyHeatmap: A Tidy Implementation of Heatmap

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

Description

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

Usage

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

## S4 method for signature '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.
