Themes

Modern

library(ggplot2)

ggplot(iris, aes(x = Sepal.Width, y = Sepal.Length, color = Species)) +
  geom_point2() +
  theme_modern()

Lucid

library(ggplot2)

p <- ggplot(iris, aes(x = Sepal.Width, y = Sepal.Length, color = Species)) +
  geom_point2()

p + theme_lucid()

Blackboard

p + theme_blackboard() 

Abyss

Palettes

This is just one example of the available palettes. See this vignette for a detailed overview of palettes and color scales.

Material design

p1 <- ggplot(iris, aes(x = Species, y = Sepal.Length, fill = Species)) +
  geom_boxplot() +
  theme_modern(axis.text.angle = 45) +
  scale_fill_material_d()

p2 <- ggplot(iris, aes(x = Species, y = Sepal.Length, fill = Species)) +
  geom_violin() +
  theme_modern(axis.text.angle = 45) +
  scale_fill_material_d(palette = "ice")

p3 <- ggplot(iris, aes(x = Petal.Length, y = Petal.Width, color = Sepal.Length)) +
  geom_point2() +
  theme_modern() +
  scale_color_material_c(palette = "rainbow")

Multiple plots

The plots() function allows us to plot the figures side by side.

plots(p1, p2, p3, n_columns = 2)

The plots() function can also be used to add tags (i.e., labels for subfigures).

plots(p1, p2, p3, n_columns = 2, 
      tags = paste("Fig. ", 1:3))

Better looking points

geom_points2() and geom_jitter2() allow points without borders and contour.

normal <- ggplot(iris, aes(x = Petal.Width, y = Sepal.Length)) +
  geom_point(size = 8, alpha = 0.3) +
  theme_modern()

new <- ggplot(iris, aes(x = Petal.Width, y = Sepal.Length)) +
  geom_point2(size = 8, alpha = 0.3) +
  theme_modern()

plots(normal, new, n_columns = 2)

Half-violin Half-dot plot

Create a half-violin half-dot plot, useful for visualising the distribution and the sample size at the same time.

ggplot(iris, aes(x = Species, y = Sepal.Length, fill = Species)) +
  geom_violindot(fill_dots = "black") +
  theme_modern() +
  scale_fill_material_d()

Radar chart (Spider plot)

library(dplyr)
library(tidyr)

data <- iris %>%
  group_by(Species) %>%
  summarise_all(mean) %>%
  pivot_longer(-Species)

data %>%
  ggplot(aes(x = name, y = value, color = Species, group = Species)) +
  geom_polygon(fill = NA, size = 2, show.legend = FALSE) +
  coord_radar(start = -pi/4) +
  theme_minimal()
