[BioC] kOverA function

Robert G.,
I have tried to use the kOverA function to filter out genes for which there 
are no
values greater than 3.8.  However, I have found that genes are not selected 
which
have values >3.8 (ie. 4.5) for 42 samples.  I have version R2.2.0 and the 
updated
Bioconductor package.

library(genefilter)
f1 <- kOverA(42, 3.8)
selected <- genefilter(kidney_exp, f1)
sum(selected)
E <- as.matrix(kidney_exp[selected,])
rownames(E) <- kidney[selected,1]

Can someone verify that this function is not working correctly?
Thanks,
