Make a table of means and frequency in r

Question

I want to make a table of means and frequency in RStudio resembling this one:

I have the exact same data as the authors of the article, but i cannot figure out how to do a resembling table in R without using excel.

Thanks!

You will get better answers if you provide the data and a [reproducible example](http://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example/5965451#5965451) of what you have tried already. — Paul Rougieux, Feb 23 '17 at 15:58

You can use the dplyr package to do this

depending on the data the code can be something like

mydata %>%    
group_by(Gender, Country) %>%    
summarise(Age = mean(age),  Weight = mean(weight), n = n() [...])

But i want the rows to be variables so the columns are divided in country, and when i run your code i get an errormessage that the variables isn't found... – Julie Ravn Feb 23 '17 at 12:35
Shouldn't be a big deal. How does the data looks like, can you add the first few lines? – Codutie Feb 23 '17 at 12:54
@Codutie you wrote `plyr` but you meant `dplyr`. – Paul Rougieux Feb 23 '17 at 16:00
