Remarks:

• The Readme was a bit minimal, a table with links to the relevant files could be useful.
• Your table on GDP by year by country was very large. You may want to truncate it.
• The unused code at the end would be easier to read if it was in a code block that did not execute. For this you can use {r chunkName, eval = FALSE}
• I like how you experimented with a non-default theme!
• The plots that your chose were informative and relevant to the task.
• Overall, I felt like you provided good information on each topic will well chosen plots and tables.

Thanks for your feedback!

Your welcome! I have a few extra comments:

• I imagine you used geom_jitter at the end to make the number of points more visible. You also could set the transparency using the argument alpha, for example alpha = 0.1. Also, my personal opinion is that jitter plots are best used for data at discrete levels rather than continuous data.
• Your cable plots were nice, but it might be worth looking at some of the parameters. Also, for html (but not md) files, you can use kableExtra to get some really impressive plots. This isn't useful for our assignments in md, but maybe for the future!
• You might want to break up your analysis into several paragraphs. However, you analysis was quite thorough, particularly for your plot of standard deviation by continent over time.
• You could use the code chunk arguments, such as fig.width to make your plots larger. The axis labels for you last plot were overlapping.
