[BioC] Problem while working with GOSim package

[Anirban Bhar]

Dear all,

I am presently using getGeneSim() of GOSim package. As an output of this
function I am getting an n X n matrix, where n is the no. of entrez ids. Now my
question is how I will get the names of the corresponding entrez identifiers for
which the matrix is generated. Because if I use a list of 1000 entrez ids, it
could be the case  that some of them are filtered out due to the annotation
problem.. 

Thanks in advance,

Best regards, 

Anirban
