R help - Jul 2008 - Converting english words to numeric equivalents

Hello,

I am trying to convert english words to numeric equivalents, e.g., abc to 123.
Is there a function or library or package for doing this in R? If not, can it be
done easily in R?

Thanks,

Oscar

Your question is very ill-posed.  What ``english word'' would  
correspond to 0?
What would the ``english word'' xyz (?!?!) correspond to?

If you can phrase a coherent question, it can probably be answered.
