Hey @OliviaTabares,

I really like the picture on your main README! And on a more practical note, the file was easy to navigate with the links to the homework folders right at the top of the file! The hw_04 README had a nice progress report; sorry to hear you had a hard time with the joining, but I liked that you added a helpful cheatsheet.

I really liked how you repeated the question under your section header, it made it very easy to figure out what you were doing. You had great commentary on the table you created, and it was very easy to visualize. The plot , again, was easy to interpret. I liked how you used the gather() function to plot multiple comparisons; I, myself, used spread() and did comparisons between two countries over time.

You tried all the joins, which was great, and provided a good cheat sheet with a great visualization component. The only suggestion I would make would be to describe it in you own words, but as you said, you ran out of time for that and added the cheat sheet.

Overall, very well done!

Cheers,

Margot

Hii @OliviaTabares ,

I thought the README file and overall organization was great. Made it really easy on my end. Thanks :)

Activity 2

• Really nice piping
• I liked that you renamed the columns of your new table as it made it a lot easier to understand
• The graph was also well done: I liked that you coloured the lines by country to help tell the visual story in a clear way as well as the use of theme_bw (it looks so much nicer). The one thing that would have made the graph better would be to add a main title to help the reader
• Just FYI: you can add two spaces to a new link and then hit enter to create a hard end (this means that the text will show up under your figures rather than awkwardly beside like in the graph). I think this makes the document look nicer.

Joins I thought your piping to create the gapminder subset was well done. I also thought it was great how you added the cheat sheet image as well as the link to the complete document. As noted, you did not have time for explanations. That said, the lack of explanations in your own words makes it hard to know if you understood how the different joins worked and when you would use them.

Overall well done. Check.

Best, Jennica

@OliviaTabares here are some comments about your homework: General data reshaping and relationship to aggregation: Yes (act 2) Join, merge, look up: Yes (act 1) Progress report: Yes Extras (optional; merge/match): No

Activity 2

• Nice approach to get/reshape your data,
• You missed to include Islas Feroe as vikings (kidding),
• I appreciate your explanation after re-shaping, in fact I liked that you took advantage of that and described some points.
• But even I liked more that you showed that in a graph, where you practiced and integrated perfectly ggplot and other functions,
• For the expectancies of the countries against each other I think plotmatrix() or ggpairs() do the same as pairs().

  Activity 1

• You succeed in the creation of both databases integration properly filter() and kable(),
• You applied properly the join...() functions,
• You showed the tables in a good way,
• Because you ran out of time you could not give explanations or round off the activity with some graphs, but any way I consider that your assignment is complete!

Your grades will be distributed later! Regards,
