The University of Chicago Color Scales — scale_color

See pal_uchicago for details.

Usage

scale_color_uchicago(palette = c("default", "light", "dark"), alpha = 1, ...)

scale_colour_uchicago(palette = c("default", "light", "dark"), alpha = 1, ...)

scale_fill_uchicago(palette = c("default", "light", "dark"), alpha = 1, ...)

Arguments

palette: Palette type. There are 3 available options: "default" (9-color palette); "light" (9-color light palette); "dark" (9-color dark palette).
alpha: Transparency level, a real number in (0, 1]. See alpha in rgb for details.
...: additional parameters for discrete_scale

) +
  geom_point(alpha = 0.7) +
  geom_smooth(method = "loess", alpha = 0.1, size = 1, span = 1) +
  theme_bw()

p2 <- ggplot(

  aes(x = depth, fill = cut)
) +
