[R] Converting english words to numeric equivalents

[baptiste auguie]

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,

baptiste
