How do I show the source code of an S4 function in a package?

Question

I used the packages topGO in R to analyze gene enrichment with the following code:

sampleGOdata <- new(\"topGOdata\", description = \"Simple session\",          


        

Answer 1

I know this is an old question, but for the sake of completeness for future searchers, there's also a function called

selectMethod

that varies from getMethod in that you can use inheritance. This is how I found source for a generic function that has multiple signatures.
