Hey R experts,
I am just beginning and learning with R. Here's the situation:
I have two different data frames, df_1 has 288 lines and df_2 has 632 lines.
The first columm of both has city names. Every city at df_1 is included at df_2, but the opposite is not true.
I need to get information from the two last columms at df_2 to df_1, but I don't know how to make the program understand that I only want information for the 288 cities contained at df_1.
Could you please help me on that?
