Generate a continuous color gradient to be colored via ggplot2's scale_fill_* mechanism

Description

This function creates a ggplot2 object that can be directly styled by adding a scale_fill_* expression. Thus, this function is particularly useful to visualize existing ggplot2 color scales.

Usage

gg_color_gradient(n = 200, ymargin = 0, title = NULL,
  title_size = 14, title_family = "", title_face = "plain",
  plot_margin = margin(title_size/2, title_size/2, title_size/2,
  title_size/2))

Arguments

n	Number of distinct color slices to be drawn
ymargin	Fraction of each swatch to be used as margin in the y direction
title	Optional title to print above the color swatches. Can also be provided via ggtitle.
title_size	Font size of the title
title_family	Font family of the title
title_face	Font face of the title
plot_margin	Margin around the plot, specified via the ggplot2 function margin

Examples

gg_color_gradient() + ggtitle("Default ggplot2 continuous color scale")
