if a vector has names then as.word() does not work #1

the names should be silently set to NULL, as they can have no meaning in the package.

also:

> rbind(a)
  a b c d e
a 5 1 2 3 4
> word(rbind(a))
Error in FUN(newX[, i], ...) : 
  invalid word: rows should be permutations of seq_len(ncol(w))

in both cases the error message is cryptic at best and misleading at worst.
