theme_prism: Prism themes

In ggprism: A 'ggplot2' Extension Inspired by 'GraphPad Prism'

Prism themes

Description

A collection of ggplot2 themes that use palettes which mirror the colour schemes available in GraphPad Prism.

Usage

theme_prism(
  palette = "black_and_white",
  base_size = 14,
  base_family = "sans",
  base_fontface = "bold",
  base_line_size = base_size/14,
  base_rect_size = base_size/14,
  axis_text_angle = 0,
  border = FALSE
)

Arguments

palette	string. Palette name, use names(ggprism_data$themes) to show all valid palette names.
base_size	numeric. Base font size, given in "pt".
base_family	string. Base font family, default is "sans".
base_fontface	string. Base font face, default is "bold".
base_line_size	numeric. Base linewidth for line elements
base_rect_size	numeric. Base linewidth for rect elements
axis_text_angle	integer. Angle of axis text in degrees. One of: ⁠0, 45, 90, 270⁠.
border	logical. Should a border be drawn around the plot? Clipping will occur unless e.g. coord_cartesian(clip = "off") is used.

Value

Returns a list-like object of class theme.

Examples

library(ggplot2)

# see ?preview_theme for a convenient function to preview ggprism themes
# before using theme_prism

## base plot
base <- ggplot(mpg, aes(x = displ, y = cty, colour = class)) +
  geom_point()

## default palette is "black_and_white"
## default base_size is 14 (compared with 11 for theme_grey)
base +
  theme_prism()

## try some other palettes
base +
  theme_prism(palette = "office")

base +
  theme_prism(palette = "flames")

## try matching the theme_prism palette with same colour palette
base +
  theme_prism(palette = "stained_glass") +
  scale_color_prism(palette = "stained_glass")

base +
  theme_prism(palette = "candy_bright") +
  scale_color_prism(palette = "candy_bright")

## change the font face
base +
  theme_prism(base_fontface = "plain")

## change the font family
base +
  theme_prism(base_family = "serif")

## base_line_size scales automatically as you change base_size
base +
  theme_prism(base_size = 10)

## but you can also change it manually
base +
  theme_prism(base_size = 16, base_line_size = 0.8)

## easily change x axis text angle
base +
  theme_prism(axis_text_angle = 45)

## add a border (need to turn off clipping)
base +
  theme_prism(border = TRUE) +
  coord_cartesian(clip = "off")

## change border thickness
base +
  theme_prism(border = TRUE, base_rect_size = 2) +
  coord_cartesian(clip = "off")
