Theme for mosaic plots — theme

Themes set the general aspect of the plot such as the color of the background, gridlines, the size and color of fonts. theme_mosaic provides access to the regular ggplot2 theme, but removes any background, axes ticks, most of the gridlines, and ensures an aspect ratio of 1 for better viewing of the mosaics. This theme also applies a bold face to axes labels and allows for the convenient rotation of category labels.

Usage

theme_mosaic(base_size = 11, base_family = "", rot_labels = 0, ...)

Arguments

base_size: Base font size. Defaults to 11.
base_family: Base font family. Defaults to "", which uses the graphics device's default font family.
rot_labels: The angle (in degrees) used to rotate category labels. Defaults to 0 degrees, relative to the current axis orientation.
...: Additional arguments passed to ggplot2::theme(). These are applied after the mosaic theme defaults and can therefore override them.

Value

A ggplot2 theme object that can be added to a plot.

Details

As with other ggplot2 extensions, themes set the general look-and-feel of the plot such as the color of the background, gridlines, the size and color of fonts. theme_mosaic() provides access to the regular ggplot2 theme, but: removes any background, axes ticks, most of the gridlines, and ensures an aspect ratio of 1 for better viewing of the mosaics. This theme also applies a bold face to axes labels and allows for the convenient rotation of category labels to avoid overlap
