A bit obscure to me.  I haven't read the fine print on topGO or GOstats, so maybe having both packages loaded at the same time is forbidden.  Anyway, the fix is easy, just run one or the other.

that suggests that topGO is not using a NAMESPACE (Adrian, your package 
would likely benefit from having one, so that you have better control 
over which functions are getting picked up). The purpose of NAMESPACEs 
is to ensure that this does not happen.  I suspect, but am not sure that 
if you load GOstats first, then topGO that you would not have trouble. 
If you have the energy to try that and report back (but with the error, 
if there is one, not a summary) that could help.
