[BioC] expresso errors for MBEI

[Ann Hess]

I am trying to use the expresso command to get MBEI values.  I get the
following errors.  Note that I was able to use expresso to get RMA and MAS
values for the same data without any errors.  Any suggestions?

**I am using R version 1.6.2 and affy version 1.1.1.

> eset3<-expresso(data,normalize.method="invariantset",bg.correct=FALSE,
	pmcorrect.method="pmonly",summary.method="liwong")

normalization: invariantset
PM/MM correction : pmonly
expression values: liwong
normalizing...done.
