I've analyzed for an investigator of my institution some expression data for DGE with limma. Afterwards, I've used limma mroast function to perform GO enrichment analysis in the same expressionSet and design.
I've found some interesting GO terms, but the investigator whose arrays I'm analyzing would like to have the results in a more graphical way, that takes into account what he calls the strength of the GO term (that I think is something like a p-value, but maybe some kind of mix between p-value and number of genes for this GO term).
I could represent these GO terms as circles with color representing this "strength", but I don't know how to connect the different circles taking into account the structure of GO.
I've read about some packages, as clusterProfiler, but I would like to use the data generated by mroast, and I've not been able to convert my mroast results into the data needed for representing them with clusterProfile.
Is there any package/function to graphically represent the data obtained with mroast?
Thank you in advance
Best regards ,
