[BioC] frmaTools library error :: makeVectorsAffyBatch() function

The issue is that you are trying to estimate between-batch residual
variances with only 1 batch:
abatch.ref <- makeVectorsAffyBatch(files.ref,
rep(1,length(files.ref)), file.dir=FILED)

I'm curious why you are making your own fRMA vectors. HGU133plus2 has
pre-made frozen parameter vectors in the hgu133plus2frmavecs package,
so you could use those to preprocess your data.

Best,
Matt
