2021-10-4 Covid19 API interaction

Yan Liu 2021/10/4

I completed a Vignettes (github repo) that demonstrates how to interact with a Covid-19 API by using a series of created functions.

Explaination

To summarize everything I did in this vignette, I built functions to interact with some of the COVID-19 API endpoints, retrieved some of the data, and explored it using tables, numerical summaries, and data visualization. The results above showed that the mortality rate decreased in the all the listed European countries after 60% population got vaccinated. Surprisingly, we did not see a clear correlation between them. The observed morality is not higher in the countries with higher cases per capita.

Writing this vignette helps me learning how to interact with an API and how to perform a basic exploratory data analysis.

Thoughts

During this project, the most difficult part is to decide which part of data I should present in the vignettes and how to design the structure of the vignettes to present the data in a logical way. I kept changing ideas during the programming which wasted a lot of time. Next time I hope I am able to understand the structure of API better and earlier, then draft a plan with detial first before working on the programming part.
