Red to Blue Color Palette

I've been trying to find a color palette that goes from a red to blue gradient. I have used scale_color_gradient(), but are there any palettes in a package that I y'all know of?

Have you tried {RColorBrewer}?

display.brewer.all(colorblindFriendly = TRUE) # View all palettes

ggplot(iris, aes(Sepal.Length, Sepal.Width))+
  geom_point(aes(color = Species)) +
  scale_color_brewer(palette = "RdBu") # Use red/blue palette

Somehow hadn’t seen that before. Thank you!
