[BioC] rowQ failed

looks like a bug-let,
the problem is that you have an integer matrix, and rowQ wants it to be 
double (but rowQ should convert internally if this is the case)

mt=matrix(1:12+0, nrow=3)
rowQ(mt, 2)

works just fine

also, please do follow the posting guide and provide a complete example 
(including all calls to library etc) and the output of sessionInfo,
