ggtheme: Complete themes

In TomeTiger/ggplot2: Create Elegant Data Visualisations Using the Grammar of Graphics

Description

These are complete themes which control all non-data display. Use theme() if you just need to tweak the display of an existing theme.

Usage

theme_grey(base_size = 11, base_family = "",
  base_line_size = base_size/22, base_rect_size = base_size/22)

theme_gray(base_size = 11, base_family = "",
  base_line_size = base_size/22, base_rect_size = base_size/22)

theme_bw(base_size = 11, base_family = "",
  base_line_size = base_size/22, base_rect_size = base_size/22)

theme_linedraw(base_size = 11, base_family = "",
  base_line_size = base_size/22, base_rect_size = base_size/22)

theme_light(base_size = 11, base_family = "",
  base_line_size = base_size/22, base_rect_size = base_size/22)

theme_dark(base_size = 11, base_family = "",
  base_line_size = base_size/22, base_rect_size = base_size/22)

theme_minimal(base_size = 11, base_family = "",
  base_line_size = base_size/22, base_rect_size = base_size/22)

theme_classic(base_size = 11, base_family = "",
  base_line_size = base_size/22, base_rect_size = base_size/22)

theme_void(base_size = 11, base_family = "",
  base_line_size = base_size/22, base_rect_size = base_size/22)

theme_test(base_size = 11, base_family = "",
  base_line_size = base_size/22, base_rect_size = base_size/22)

Arguments

base_size	base font size
base_family	base font family
base_line_size	base size for line elements
base_rect_size	base size for rect elements

Details

theme_gray

The signature ggplot2 theme with a grey background and white gridlines, designed to put the data forward yet make comparisons easy.

theme_bw

The classic dark-on-light ggplot2 theme. May work better for presentations displayed with a projector.

theme_linedraw

A theme with only black lines of various widths on white backgrounds, reminiscent of a line drawings. Serves a purpose similar to theme_bw. Note that this theme has some very thin lines (<< 1 pt) which some journals may refuse.

theme_light

A theme similar to theme_linedraw but with light grey lines and axes, to direct more attention towards the data.

theme_dark

The dark cousin of theme_light, with similar line sizes but a dark background. Useful to make thin coloured lines pop out.

theme_minimal

A minimalistic theme with no background annotations.

theme_classic

A classic-looking theme, with x and y axis lines and no gridlines.

theme_void

A completely empty theme.

theme_test

A theme for visual unit tests. It should ideally never change except for new features.

Examples

mtcars2 <- within(mtcars, {
  vs <- factor(vs, labels = c("V-shaped", "Straight"))
  am <- factor(am, labels = c("Automatic", "Manual"))
  cyl  <- factor(cyl)
  gear <- factor(gear)
})

p1 <- ggplot(mtcars2) +
  geom_point(aes(x = wt, y = mpg, colour = gear)) +
  labs(title = "Fuel economy declines as weight increases",
       subtitle = "(1973-74)",
       caption = "Data from the 1974 Motor Trend US magazine.",
       tag = "Figure 1",
       x = "Weight (1000 lbs)",
       y = "Fuel economy (mpg)",
       colour = "Gears")

p1 + theme_gray() # the default
p1 + theme_bw()
p1 + theme_linedraw()
p1 + theme_light()
p1 + theme_dark()
p1 + theme_minimal()
p1 + theme_classic()
p1 + theme_void()

# Theme examples with panels

p2 <- p1 + facet_grid(vs ~ am)

p2 + theme_gray() # the default
p2 + theme_bw()
p2 + theme_linedraw()
p2 + theme_light()
p2 + theme_dark()
p2 + theme_minimal()
p2 + theme_classic()
p2 + theme_void()
