An alternative grey theme (for ggplot2)

Source: R/plot_themes.R
theme_grau.Rd

theme_grau provides an alternative grey theme for use in ggplot2 and unikn contexts.

Usage

theme_grau(
  col_title = grey(0, 1),
  col_line = pal_grau[[3]],
  base_size = 11,
  base_family = "sans",
  base_line_size = base_size/22,
  base_rect_size = base_size/22,
  axis_ticks_mm = 2
)

Arguments

col_title

Color of title elements (optional). Default: col_title = grey(0, 1) (i.e., "black"). Consider using col_title = unikn::pal_seeblau[[4]].

col_line

Color of line elements used for axis ticks (optional). Default: col_line = pal_grau[[3]] (i.e., medium grau).

base_size

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

base_family

Base font family (optional, character). Default: base_family = "sans". 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.

axis_ticks_mm

Length of axis ticks (in mm). Default: axis_ticks_mm = 2.

Details

theme_grau is no-nonsense, but fills panel backgrounds in "grau" (specifically, pal_seeggrau[[1]]).

This theme works well for dark colors and bright color accents, but is of limited use with transparent colors.

theme_unikn for default theme; theme_bwkn for a bw theme; theme_minikn for a minimal theme.
