Fig. 4From: GOexpress: an R/Bioconductor package for the identification and visualisation of robust gene ontology signatures through supervised learning of gene expression dataHeat map and hierarchical clustering of treatment groups using expression data from genes associated with the top-ranked GO term. The heatmap_GO visualisation function summarises expression level for all genes present in the ExpressionSet and associated with chemokine activity (GO:0008009).
