[BioC] nsFilter cutoff

Hi,

I am finding the nsFilter IQR cutoff somewhat confusing.

It says it is using IQR with a default cutoff of 0.5.

This gives the impression that if you line up the data and take the 
value between the 0.25 and 0.75 quantiles, you would keep the probeset 
if this value was < 0.5

However this is not the case, so I would like to know how exactly does 
this work?

Regards,

James
