I can not find any solution for my problem. I want to merge two data frames like these for example:
country people per m
Aruba 5
Ireland 3
Spain 2
country kg per person
Aruba 80
New Zealand 75
Germany 60
Spain 66
Now I want to merge them make a data frame which looks like that:
country people per m kg per person
Aruba 5 80
Ireland 3 NA
Spain 2 66
New Zealand NA 75
Germany NA 60
I hope you can give me some tips.
Thank you
