Adjust Theme Sizes in ggplot2

This function adjusts the sizes of various theme elements in a ggplot2 plot. It takes a single argument which is the base size for geom_text, and it calculates the theme sizes based on this.

Usage

tar_ggplot_font_size(geom_text_size = 7)

Arguments

geom_text_size

The base size for text elements in `geom_text`. Default is 7.

Value

A `theme` object that can be added to a ggplot.

Details

Always add the same size as in geom_text, then all fonts will have the same size. Default size is 7. If there is no geom_text we can control the font size of axis, legend, title and text with this function.
