Hi,
I have two data-frames like: A: USA 3.2 Canada 4.7 Austria 1.5 Iran 0.3 China 3.8 Japan 3.0 B: Austria 17 Iran 22 Angola 29 Japan 32 England 11 Now I want to merge this two data.frames to one - but I only want entries for the countries I have complete observations for; so the final data.frame should look like this: C: Austria 1.5 17 Iran 0.3 22 Japan 3.0 32 How can I do this? ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
