Hi, I'm using the GeneAnswers package and its geneAnswersConceptRelation function to display Gene Ontology enrichments for my lists of genes in the form of connected networks. I find the output very informative but I'm having a hard time in understanding what the sizes of circles and the colours of cirlces and arrows in the network represent. My guess is that the intensity of red in circles reflects the adjusted p-value of the enrichment while the size could be proportional to the number of the genes associated with that term. Also I have no clue about what is the meaning of the different colours of the arrows connecting the circles (I've stumpled upon grey, light blue, orange and purple so far). I can't find anything in the package documentation, so I was wondering if somebody could point me to the right docs. Thanks very much.
