[BioC] question about QCReport

Hi Yan:

Although we talked offline, I am responding to your message here.

It would be nice if you send the output of sessionInfo() and the code 
that can reproduce the error.

Looking at the function QCReport
 > QCReport
function (object, file = "AffyQCReport.pdf", ...)
    pdf(file = file, width = 8, height = 11, onefile = TRUE)
    plot.window(c(1, 1), c(0, 1))

Your error comes from qc(object). If you can re-run the code without the 
line plot(qc(object)), you would get the other results.

Another thing to note is that poplar annotation is not available at 
bioconductor. Looking at 
http://www.bioconductor.org/packages/release/data/annotation/, there is 
a poplarcdf and poplarprobe but not a poplar.db. This post on bioc 
mailing list in 2007 describes the difficulty in building a poplar 
annotation package. Perhaps the same problems apply even now.


Good luck.
