4 years ago Despite the lack of polish, this is great work. Here are my comments:
- At the beginning of a code chunk add {r, message=FALSE,warning=FALSE} to suppress messages and warnings in HTML. When you knit your file, go through the HTML and see if some code chunks are displaying the text you don't want (such as in the sections Loading Covid Data, or Proportional Map). If there is such text, remove it with the code I mentioned above.
Q1: When do I need to load a library, and when do I just need to load a package? A1: A collection of functions, such a ggplot2, is called a package. library is a function you use to load a package - library(ggplot2). In other coding languages, packages are usually called libraries, so some people use these terms interchangeably. You need to load a package every time (once per file) you want to use a function from a package. If you forgot to load it, you'll get an error.
Q2: Plots side by side. A2: In grid.arrange(aea_africa, nab_africa, nrow = 1), instead of nrow=1, use ncol=2.
Q3: Would appreciate a workshop or 101 on data cleaning. A3: https://vis-2129-f2020.github.io/tutorials/Data_cleaning
Q4: What would be your recommendation on how to not have the circle overwhelm South Africa? Q4: 1) Make it transparent, 2) change the number of cases of SA in your data and add a note in the map saying you changed it, 3) or set the sizes manually with scale_size_continuous(name="Name", range = var, labels...), where var contains case numbers for all countries, but changed for SA (essentially the same suggestion as the previous one, just instead of going back to your data set, you set it in ggplot).
Q5: Why is legend.position not working? Q5: It should be theme(legend.position="left")
Re questions about errors, please upload the csv file so I can recreate them.
Thank you!
