 ### The design of the composite 
 To create a composite, we use the `wrap_plots()` function from `patchwork`. 
 The name is somewhat self-explanatory as for wrapping plots into a larger one.

 The way `wrap_plots()` matches sub-panel names to parts A, B, and C is by the order. 
 In this case, the first sub-panel name (A1) provided is part A, and so on.

 For example, vector `c(0.3, 1)` passed on to the `widths` option specifies that the 1st column should be 0.3 of the width of the 2nd column.  
 Notice we only 2 rows and columns, so the heights and widths vectors each have 2 numbers. 
 However, if the dimension of the design is different, the heights & widths vectors must have matching dimension too.
