Make a data frame

From The World Factbook construct a data frame in which units (rows) are world countries with names from the “book” and variables (columns):

the first variable V1 contains the two-character code of the country ISO - for labels in visualizations;
the second, third, fourth, and fifth variables are as given in the table (select a row from the table and make me a note for confirmation or select your own variables V2, V3, V4, and V5 for which you expect that are somehow related, and make me a note for confirmation);
if you find it useful for your exploration you can add additional variables from the “book”.

For visual inspection the additional variable region (North America, Central America, South America, Europe, Africa, Middle East, Central Asia, South Asia, East & Southeast Asia, Australia & Oceania, Antarctica) would be very useful - it can be constructed from the map on the entry page and region's countries lists on the next level.

Save the created data frame as a CSV file.

Explore the collected data. For visualization on a map see Maps or rworldmap.

Write a report and save it as a PDF file. Put the report and CSV file into a ZIP file and send it to me.

Hint: The factbook data are available as a JSON file at GitHub / Download

> library(jsonlite)
> J <- fromJSON(readLines("factbook.json"))
> str(J,max.level=2)
> J$countries[[4]]$data$name
[1] "Albania"
> J$countries$albania$data$name
[1] "Albania"
> names(J$countries)
> names(J$countries$albania$data)
