On windows, the 'mode' argument to download.file() needs to be "wb" (write

The file is downloaded, but oligo::read.celfiles() returns the following
error:
Error in checkChipTypes(filenames, verbose, "affymetrix", TRUE) :
End of gz file reached unexpectedly. Perhaps this file is truncated.
Moreover, if I try to delete it after using download.file(), I get a
warning that permission is denied. I can only remove it using Windows file
explorer after I closed the R session, indicating that the connection is
still open. Yet, showConnections() doesn't show any open connections
either.
Session info below. Note that I started from a completely fresh R session.
oligo is needed due to the specific file format of these gz files. They're
not standard tarred files.
