[BioC] median of the NUSE value

[kfbargad at ehu.es]

Dear list,

I am using affyPLM for my QC, and am trying to obtain the median of 
the NUSE values for my chips.

if I type 
>NUSE(Pset, main = "NUSE values") 
I get the NUSE boxplot

but if I type
> NUSE(Pset, type = "stats")
Error in match.arg(type) : 'arg' should be one of plot, values
or
> NUSE(Pset, type = "values")
Error in x at weights[which, ] : incorrect number of dimensions
In addition: Warning messages:

2: longer object length

3: the condition has length > 1 and only the first element will be 
used in: if ((model == (PM ~ -1 + probes + samples)) | (model == (PM ~

Any suggestions??

Also, is it possible to colour the boxes of the boxplot? I have so far 
been using 
boxplot() for Pset with the argument "col", but it does not work for 
NUSE()


Thanks in advance,

David
