  Would you mind to be more precise?
  I have just checked your example on a machine with rw0613b installed
  and the results seems correct: abcnon returns a list that you can see
  in the standard way:  
  > results <RETURN>

  There are only one thing that I cannot understand in your example.
  rw0613b is the binary version for Win95/WinNT which support
  long file names. Hence, the name of the package should be
  "bootstrap" not "bootstra". "bootstra" is the truncated name
  in the Win3.1/Win32s version (rwin31b). I have not checked
  the archives in CRAN but the original one at
  seems correct.
  Anyway, this should not change the results. rwin31b is different
  from rw0613b only for the name mangling (long file names -> 8.3 names).
  Indeed, I could run your example with rwin31b, too.
