Note that you have to either transform them into .txt files, or find a # package with a function that can open xlsx files. These files contain data on # literaty (% of people >15 years old) per country per year, and similar data # for consumption of alcohol (average per adult). ## TASK 2 ## # Choose a recent year and 10 countries of your interest, and make a barplot in # which you compare literacy rates between the countries. ## TASK 3 ## # Make a similar barplot for alcohol comsumption and save it as a jpeg or pdf # file. ## TASK 4 ## # Choose a recent year for the literacy dataset that has a good amount of data, # and a similar year for the alcohol dataset. Now make a scatterplot relating # the two variables. Note that the names of the countries need to match in both # datasets. Some countries might be in one dataset but not the other, and might # need to be removed ## TASK 5 ## # Use the function lm to fit a regression to this relationship, saving the # results into an object. Now, use the function summary on that object to print # a summary of the results on the screen.
