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, and fourth variable 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 and V4, and make me a note for confirmation);
if you find 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.
