Is it possible to alter the format of an individual facet plot? For example, using the sample code below, can one change the color of the title or background for the cyl=8 plot?
library(ggplot2)
ggplot(mtcars, aes(x=gear)) +
geom_bar(aes(y=gear), stat="identity", position="dodge") +
facet_wrap(~cyl)
