thesis - data presentation EUProfiler 2009

Hello world

How many users from each country?

table(d$country)
d[,.N,by=id]

There’s not an equal number of issues for each user, max is 28, but some had missing values for some of the issues, I suppose the NAs.

Data visualization

# do column histogram, distribution of "value", facet_wrap by "country". used ..density.. to avoid the different count among countries
ggplot(data=d, aes(d$value,  ..density..)) + geom_histogram(binwidth=5) +
  facet_wrap( ~ country, ncol=4)
