this code, works perfectly 
   temp <- merge(travel, city, by.x="Source", by.y="cod")
   result <- merge(temp, city, by.x="Destine", by.y="cod") 

The problem was the construction of the data frame, had a parenthesis in

I tried to delete the post, but i don't could.
  As I have little experience in R, I still do some mistakes.
I use read.table to load the data frame, the way in the post, it was quickly
that  i found to describe the problem.
  The forum has been a great help for me.
