Publication-Quality 'ggplot2' Themes.

ggrefine

The objective of ggrefine is to provide complete themes for publication-quality ‘ggplot2’ visualisation. Functions are provided to modify these based on the positional axis scales and orientation of a particular plot.

Installation

Install from CRAN, or development version from GitHub.

install.packages("ggrefine") 
pak::pak("davidhodge931/ggrefine")

Theme

The themes are built to work with the refine functions in that they have all axis and panel grid elements.

They can also be customised easily.

The theme_grey function has a smart panel_grid_colour default that is derived from the panel_background_fill.

To ensure ggrefine theme_* functions are preferred over ggplot2 functions:

• run library(ggrefine) after the ggplot2 library is loaded, or
• use conflicted::conflict_prefer_all(winner = "ggrefine"), or
• do not load ggrefine, but instead use ggrefine::theme_grey() etc.

  ) +
  scale_y_continuous(expand = expansion(mult = c(0, 0.05)))

Refine

A series of refine functions are provided.

The premise is that it is useful to set themes that have all axis and panel grid elements - and then adjust depending on the positional axis scales and orientation of a particular plot.

The refine functions are organised and named by:

• axis: classic_*, modern_*, minimal_*, and void_*.
• panel grid: *_drift, *_flow, *_drop, *_keep.

These functions then remove or not particular axis and panel grid components for different positional scales (and the intended orientation of the plot).

  panel_grid_colour = jumble::grey,
  axis_line_colour = jumble::red,
