I didn't see BAR file parsing functionality in the affxparser package (but
it is in the package description, I agree).

You can, however, write a pretty simple little parser for this format using
simple R commands.  Open the file in binary mode and use readBin, stepping
through the format description.  It is not fast, but it works OK.
