Hi,

I have used the enrichMap() function of the DOSE package to visualize enrichment results from the enrichPathway() function of the ReactomePA package. I assume that edge line thickness represent the overlap between connected nodes, that node color represent the significance of the enrichment and that node size corresponds to the number of differentially expressed genes in the gene set. However, I cannot find a description of this in the documentation of the DOSE or the ReactomePA package. Please provide a reference that describe the edge and node properties, and that is suitable for the enrichMap() function of the DOSE package.

Many thanks for any help and guidance.
