Hi,
I am getting an error in genefilter:

data(golub)
> eset
Expression Set (exprSet) with 
22300 genes
42 samples
phenoData object with 1 variables and 42 cases
varLabels
sample: arbitrary numbering
> library(genefilter)
> f1 <- pOverA(0.25, lob2(100))
> f2 <- function(x)(IQR(x) > 0.5)
> ff <- filterfun(f1,f2)
> selected <- genefilter(eset,ff)
Error in sum(x > A) : couldn't find function "lob2"

Can someone point out to solve this matter?
Thanks,
Lana
