Examples

Discrete palette examples using ggplot2

library("ggplot2")
ggplot(mtcars, aes(factor(cyl), fill=factor(vs))) +  geom_bar() +
  scale_fill_manual(values = vangogh_palette("SelfPortrait")) 

ggplot(mtcars, aes(mpg, disp)) + 
  geom_point(aes(col = factor(gear)), size = 4) + 
  scale_color_manual(values = vangogh_palette("Cypresses"))

ggplot(iris) + 
    aes(Sepal.Length, Sepal.Width, color = Species) + 
    geom_point(size = 3) + 
    scale_color_manual(values = vangogh_palette("CafeDeNuit"))

• Discrete palettes pick 1:n colors from the palette vector (n=5 for this package as 5 colors were curated for each palette)

• Default color selection starts from colors at the extreme left and ends at the extreme right of the color palette.

Continuous palette examples

Generate a continuous palette from the given discrete palettes

x <- vangogh_palette("Chaise", 1000, "continuous")
x

• colorRampPalette()is used to a set of colors to create a new continuous palette.

Heatmap examples

oldpar <- par(mar = c(1, 1, 1, 1))
par(mar = c(1, 1, 1, 1))
pal <- vangogh_palette("SunflowersLondon", 21, type = "continuous")
image(volcano, col = pal)
par(oldpar)

ggplot(faithfuld) +
  aes(waiting, eruptions, fill = density) + 
  geom_tile() + 
  scale_color_manual(values = vangogh_palette("CafeTerrace")) 

scale_colour_vangogh() and scale_fill_vangogh() examples

ggplot(data = mpg) +
   geom_point(mapping = aes(x = displ, y = hwy, color = class)) +
   scale_colour_vangogh(palette="StarryRhone")

ggplot(diamonds) + geom_bar(aes(x = cut, fill = clarity)) +
   scale_fill_vangogh(palette = "StarryNight")
