Hi Peder,
I am trying to use your script for doing two channel miRNA exiqon data and i
am ending up with following error.


Cy3.norm <-
apply(cy3.channel,2,function(v){tapply(v,names(v),function(x){median(x,na.rm=TRUE)})})

Error in tapply(v, names(v), function(x) { :
  arguments must have same length

any help is appreciated

Thanks
Ashwin
