Hi, I am working on the following file:
> str(elencositi) 'data.frame': 641 obs. of 2 variables: $ indirizzo.sito: chr "10ahora.com.ar" "abceconomia.co" "accmag.com" " actu.orange.fr" ... $ nome.sito : chr "10ahora" "ABC economia" "Acc Magazine" "Orange Actu" ... > head(elencositi) indirizzo.sito nome.sito 1 10ahora.com.ar 10ahora 2 abceconomia.co ABC economia 3 accmag.com Acc Magazine 4 actu.orange.fr Orange Actu 5 affaires.lapresse.ca La Presse 6 agipapress.blogspot.it Agigapress Which is regularly updated and I consequently need to update a procedure that takes elencositi data to update dati$FONTE as indicated below: dati$FONTE <- ifelse(dati$FONTE=='10ahora.com.ar','10ahora',dati$FONTE) dati$FONTE <- ifelse(dati$FONTE=='abceconomia.co','ABC economia',dati$FONTE) dati$FONTE <- ifelse(dati$FONTE=='accmag.com','Acc Magazine',dati$FONTE) Currently I am using a time consuming procedure involving Excel to update that, but how can I make that automatic?
