Please ask questions about Bioconductor packages on the Bioconductor
mailing list

  http://bioconductor.org/docs/mailList.html

my guess would be that 'covdesc' is not formatted properly, and that no
files are actually merged. You might try

  debug(read.affy.merged)
  read.affy.merged()

and step through as described in ?browser.
