As you point out, my proposed function does not verify an equivalence,
and it is not restricted to english words. I'm probably too keen to
see questions that call for an answer with relaxed assumptions
(understand, that i can manage).
Cheers,

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?
