[BioC] error in genefilter?

[Kasper Daniel Hansen]

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.
