I was working on methylation profiling data. I tried to find the gene ontology related to identified DMRs using gometh function.
The command I gave is:
gst <- gometh(sig.cpg=sigCpgs, all.cpg=allcpgs, collection = "GO",plot.bias = FALSE, prior.prob = TRUE)
But I got the error like this.
Error in BiasedUrn::pWNCHypergeo(S[i, 1 + j], S[i, "N"], Total - S[i, : Invalid value for odds In addition: Warning message: In alias2SymbolTable(flat$symbol) : Multiple symbols ignored for one or more aliases
