Dear all,

I’m a problem with aCGH package. I use the R 2.4.1 version and when I give
this instruction:

 

>
ex.acgh<-aCGH.process(ex.acgh,chrom.remove.threshold=24,prop.missing=0.25,un
mapScreen=FALSE,dupRemove=FALSE)

 

I have this problem:

 

Errore in apply(log2.ratios, 2, function(col) mean(is.na(col)) >
sample.quality.threshold) : 

        dim(X) deve avere lunghezza positiva

 

 

Can you explain me the reasons? I can’t go on!

 

Thaks a lot

Michela
