Setting the background colour of a ussc ggplot2 graph

All ussc themes have a transparent background which means that you can set the background colour of a graph by using developer arguments. To do this, append a CSS style sheet in the R Markdown YAML (which affects the entire HTML document) or write r for a specific graph, replacing colour with a HEX code or rgb code. Note that if you do not set a background colour, theme_ussc() and other variations in the ussc package will default to a white background.

Example 1

r

ggplot(iris, aes(Sepal.Width, Sepal.Length, colour = Species)) + 
  geom_point(size = 4, alpha=0.4) +  
  theme_ussc_dark() + 
  labs(title="Univers Header", 
       x="Univers Font: Sepal Width", 
       y="Univers Font: Sepal Length", 
       caption = "The data is from the Iris R package and is an example.") + 
  scale_colour_ussc("blue", reverse=TRUE)

Example 2

r

ggplot(data=iris, aes(x=Sepal.Length, y=Sepal.Width, color=Species)) + 
  geom_point(aes(shape=Species), size=1.5) + 
  xlab("Sepal Length") + 
  ylab("Sepal Width") + 
  ggtitle("Scatterplot with smoothers") + 
  scale_colour_ussc("main") + 
  theme_ussc() + 
  geom_smooth(method="gam", formula= y~s(x, bs="cs"))
