So, I would like connect the two vehicles oof the first dataframe with the best vehicles in the second one.
The result should be 2 columns, the first with the 2 vehicles of the dataframe 1 and the second column with the best vehicles from the dataframe 2.
I would like to intersect the dataframe "x" and "y", through a common data site in the vector "z".
The final result should be connect the 2 vehicles in the dataframe "y" with the most coincident vehicles site in the dataframe "x"
The idea is use the vector "z" as a help for both dataframe to look for the coincident strings between the both dataframes.
