Changing the Color Scheme of the Given Theme

In this section, we'll change the color scheme and use a different palette. Let's begin by implementing the following steps:

1. Use the predefined theme, theme_bw, and create the same plot as in the previous example:

2. The ?scale_fill_brewer command provides the following palettes (the code snippets are included):
   

3. Try using Spectral, Pastel1, and Oranges to produce the following plots:

p4 + scale_fill_brewer(palette="Spectral") 

Let's take a look at plot 1:
