custom_theme: Customized ggplot2 theme

In emwozniak/reportR: Miscellaneous tools to stylize reports

Description

This function makes presentation-ready ggplot2 plots when added as a theme to a ggplot2 function call.

Usage

custom_theme(base_size, base_family)

Arguments

base_size	Base font size for the plot. Optional; defaults to 18.
base_family	Font family for the plot. Optional; defaults to "serif".

Value

Returns a theme to stylize a ggplot2 graph.

Note

At present, an extra line space is needed after the plot title and before the x- and y-axis labels to make the plot look right. This is weird and needs fixing. See the example.
