Those look like filenames generated by the tempfile() function.  Those 
would normally be in the tempdir() directory.  If you have some 
environment variable (TMPDIR, TMP, TEMP) set to ".", they could be 
created in the top level of your package.  Alternatively, if you are 
using basename() on tempfile() you'll get the same sort of thing.
