Well, i mean that *I* would have typed  "02" by chance.

I read, but didn't fully understand the sentence :
" Factors, raw vectors and lists are converted to character vectors,
  and then ‘x’ and ‘table’ are coerced to a common type (the later
   of the two types in R's ordering, etc",

I thought that the eventual common type would be integer, not character.

But it's clear, now.

Thanks again,
