And how did we get Santa's coordinates?
Since he didn't share his location, we created a function (get_random_night_coords()) to randomly generate coordinates of a location with a current local time between 11pm and 3am, assuming those are his working hours!
Close enough!

Both of these figures are created with ggplot2, and use a saved PNG file of Santa.
geom_image() from {ggimage} places the image at specified coordinates, reading from the file path.
Here's the ggplot code for the second figure:

Want to further customize colours? 🎨
The example above uses the same colour palette for each plot, with scale_fill_brewer().
For custom colours, you can also define a palette inside scale_fill_manual() - or as a separate object that you refer to (as discussed yesterday).

🎄Day 21: Ggplot efficiency part 3🎄
Need many plots with the same style/formatting but slightly different inputs?
💡Create a custom ggplot function!
Define your plot upfront in the function, with all the long formatting code. Then run the function for each new plot with different inputs.

Visualizing the same variables in different ways (e.g. sex by time/place)?
💡Tip: Easily standardize colour palettes by defining them once at the start of your code.
Then reuse the palettes within scale_fill_manual() or scale_color_manual() across plots.

Do you need a consistent plot style for a document?
Try theme_set()🎨
Define the look of fonts, grid lines, backgrounds, axis text etc once inside theme_set(). This will apply to all subsequent ggplots in your R session. No need for long theme() code per plot!

Epis know well that missingness can skew analyses, so needs careful review. No fear, {naniar} can help! E.g.:
☑️pct_miss_case(): to check % of rows with NAs
☑️gg_miss_var(): to quickly visualize missingness by column
