Theme based on Few's "Practical Rules for Using Color in Charts"

Source: R/few.R
theme_few.Rd

Theme based on the rules and examples from Stephen Few's Show Me the Numbers and "Practical Rules for Using Color in Charts".

Usage

theme_few(base_size = 12, base_family = "")

Arguments

base_size

base font size, given in pts.

base_family

base font family

Value

A ggplot2 theme object (class theme).

Palettes

The theme sets few_pal() for discrete color and fill scales and few_shape_pal() for shape as the default palettes, so a plot draws in the theme's colors without a matching scale. A scale_*() added to the plot still takes precedence.
