Review of homework

Hi Kenneth,

I removed setting a key in the merge command, because you already set the key earlier, so this change should make no difference. Also, it was a bit tricky to see the results in the Rpres format (the information would get cut off on the bottom of the screen) so it might be better to use the Rmd format in the future. Overall, I thought it was great! I wasn't sure how to combine/join all the datatables together in one command, so it was cool seeing how you approached the problem.

I noticed for some reason that I could run your code from the Rpres file without being in the working directory, but the presentation threw an error when I tried previewing it. I'm not sure why that might happen...

Best,
Katie
