Dear list,

when I try to read the Illumina beadarray control probe profile using
readBeadSummaryData

library(beadarray)
dataFile = "Spag4_data.txt"
qcFile = "Spag4_con.txt"
BSData = readBeadSummaryData(dataFile = dataFile, dec=",", qcFile = qcFile,
skip = 0, qc.skip = 0)

I get

Error in if (!is.na(typeCol)) { : argument is of length zero

Does anyone know what this could mean?
The error must be related to the qcFile, when I skip reading it everything
works as expected...

Many thanks,

Moritz (Fellow, University of Bonn, Germany)
