A ggplot2 Theme Using a Unified AAGI Style and Typography for Plots

This theme follows a standard AAGI style including typography guidelines that uses (hopefully) sensible defaults for ggplot2 graphics.

Usage

theme_aagi(
  base_size = 9,
  major_grid = FALSE,
  minor_grid = FALSE,
  border = FALSE,
  ...
)

Arguments

base_size

Numeric. The figure's base size, set to 12 by default. For presentations using a larger base_size will make the fonts larger and more suitable for presentation slides, e.g., base_size = 24.

major_grid

Boolean. Include major gridlines in the panel. Defaults to FALSE with major gridlines, including those between facets not included.

minor_grid

Boolean. Include minor gridlines in the panel. Defaults to FALSE with minor gridlines not included.

border

Boolean. Include a border around the figure on all four sides, i.e., x-axis, y-axis, top and right sides all will have a black border not just x-axis and y-axis. Defaults to FALSE with only the x-axis and y-axis being outlined in dark grey.

...

Other arguments as passed along to ggplot2::theme().

Examples

library("ggplot2")

# Plotting discrete values
p1 <- ggplot(mtcars) +
  geom_point(aes(
    x = wt,
    y = mpg,
    colour = factor(gear)
   )) +
  facet_wrap(~ am)

p1 + theme_aagi()


# Plotting continuous values
df <- reshape2::melt(outer(1:4, 1:4), varnames = c("X1", "X2"))

p2 <- ggplot(df, aes(X1, X2)) + geom_tile(aes(fill = value)) +
  geom_point(aes(size = value))
p2 + theme_aagi()


# Using a larger base size for presentation slides
p1 + theme_aagi(base_size = 24)


# Plotting using minor gridlines
p1 + theme_aagi(minor_gridlines = TRUE)


# Plotting using major gridlines
p1 + theme_aagi(major_gridlines = TRUE)


p1 + theme_aagi(border = TRUE)


# Plotting with both gridlines and border
p1 + theme_aagi(minor_gridlines = TRUE,
                       major_gridlines = TRUE,
                       border = TRUE)
