[BioC] beadarray_1.7.6. problem/error with readBeadSummaryData()

[Christian Kohler]

Dear Bioconductor-list,

I recently started to go in for analysing Illumina (BeadChip) datasets
with the help of the 'beadarray' package.
As an Example R-script (within BeadSummaryExample) is provided, the
introduction to this topic is quite straightforward.

Until today, I used 'beadarray' in version 1.7.0 and the code snippets
of the example script worked out fine.

With 'beadarray' version 1.7.6. I experienced the following problem:

>BSData <- readBeadSummaryData(dataFile, qcFile=qcFile,
sampleSheet=sampleSheet,skip=7, columns=list(exprs="AVG_Signal",
se.exprs="BEAD_STDEV", >NoBeads="Avg_NBEADS"),
qc.columns=list(exprs="AVG.Signal", se.exprs="SeqVAR"),qc.sep=","
,sep=",", qc.skip=7, annoPkg="illuminaHumanv1")
>Error in `row.names<-.data.frame`(`*tmp*`, value = "ProbeID") :
> invalid 'row.names' length

Now, I am just wondering if other 'beadarray'-users came across this error .
