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?

Hi Lana Guessing your intentions I would say you need to change f1 <- pOverA(0.25, lob2(100)) to f1 <- pOverA(0.25, log2(100)) Note that R complains that it cannot find the function lob2. The first thing to do is doublecheck one's own input.
