theme_ds4psy: A basic and flexible plot theme (using ggplot2 and unikn).

Description

theme_ds4psy provides a generic ds4psy theme to use in ggplot2 commands.

Usage

theme_ds4psy(
  base_size = 11,
  base_family = "",
  base_line_size = base_size/22,
  base_rect_size = base_size/22,
  col_title = grey(0, 1),
  col_txt_1 = grey(0.1, 1),
  col_txt_2 = grey(0.2, 1),
  col_txt_3 = grey(0.1, 1),
  col_bgrnd = "transparent",
  col_panel = grey(1, 1),
  col_strip = "transparent",
  col_axes = grey(0, 1),
  col_gridx = grey(0.75, 1),
  col_gridy = grey(0.75, 1),
  col_brdrs = "transparent"
)

Arguments

base_size

Base font size (optional, numeric). Default: base_size = 11.

base_family

Base font family (optional, character). Default: base_family = "". Options include "mono", "sans" (default), and "serif".

base_line_size

Base line size (optional, numeric). Default: base_line_size = base_size/22.

base_rect_size

Base rectangle size (optional, numeric). Default: base_rect_size = base_size/22.

col_title

Color of plot title (and tag). Default: col_title = grey(.0, 1) (i.e., "black").

col_txt_1

Color of primary text (headings and axis labels). Default: col_title = grey(.1, 1).

col_txt_2

Color of secondary text (caption, legend, axes labels/ticks). Default: col_title = grey(.2, 1).

col_txt_3

Color of other text (facet strip labels). Default: col_title = grey(.1, 1).

col_bgrnd

Color of plot background. Default: col_bgrnd = "transparent".

col_panel

Color of panel background(s). Default: col_panel = grey(1.0, 1) (i.e., "white").

col_strip

Color of facet strips. Default: col_strip = "transparent".

col_axes

Color of (x and y) axes. Default: col_axes = grey(.00, 1) (i.e., "black").

col_gridx

Color of (major and minor) panel lines (through x/vertical). Default: col_gridx = grey(.75, 1) (i.e., light "grey").

col_gridy

Color of (major and minor) panel lines (through y/horizontal). Default: col_gridy = grey(.75, 1) (i.e., light "grey").

col_brdrs

Color of (panel and strip) borders. Default: col_brdrs = "transparent".

Value

A ggplot2 theme.

Details

The theme is lightweight and no-nonsense, but somewhat opinionated (e.g., in using transparency and grid lines, and relying on grey tones for emphasizing data with color accents).

Basic sizes and the colors of text elements, backgrounds, and lines can be specified. However, excessive customization rarely yields aesthetic improvements over the standard ggplot2 themes.

unikn::theme_unikn inspired the current theme.

Other plot functions: plot_charmap(), plot_chars(), plot_fn(), plot_fun(), plot_n(), plot_text(), plot_tiles(), theme_clean(), theme_empty()
