Subject: How do I best create a R procedure from a R file?
In-Reply-To: <CABQyo84onPdGV-Kyb8mNKZodY8meb4GsCNveE0eckNMS6G6ZCA@mail.gmail.com>
Rough sketch:
lookup.vec <- elencositi$nome.sito
names(ookup.vec) <- elencositi$indirezzo.sito
dati$FONTE <- lookup.vec(dati$FONTE)
This, however, assumes that elencositi has all the values that con occur.
