heatmaps2GO

This repository contains R code to extract gene ID <-> GO term associations from different databases and to display the set of genes annotated to a given set of GO terms as a heatmap. Two non-trivial aspects of this simple endeavour are:

1. to break the input gene list down into non-overlapping gene sets, such that each set is primarily composed of genes annotated to one single input GO term
2. to display the gene sets defined by (1.) as as stacked sub-matrices (and in general to experiment with features of ComplexHeatmap)
