[BioC] affycomp hgu133 assessment error

[Ariel Chernomoretz]

Dear list,

I get the following error when trying to run affycomp on rma expressions of 
the hgu133a spike in experiment,

> s.rma  <-read.newspikein("eset_hgu133a/rma133.csv")
> a.rma  <-assessSpikeIn2(s.rma,method.name="rma")
Performing 3 assessments that will take a few secondsError in 
exprset[-spikein, ] : only 0's may mix with negative subscripts

The command runs smoothly on hgu95a data, though 
Any help would be greatly appreciated
regards,
Ariel./
