Additional Themes and Theme Components for ‘ggplot2’

This is a very focused package that provides typography-centric themes
and theme components for ggplot2.

The core theme: theme_ipsum (“ipsum” is Latin for “precise”) uses
Arial Narrow which should be installed on practically any modern system,
so it’s “free”-ish. This font is condensed, has solid default kerning
pairs and geometric numbers. That’s what I consider the “font trifecta”
must-have for charts. An additional quality for fonts for charts is that
they have a diversity of weights. Arial Narrow (the one on most systems,
anyway) does not have said diversity but this quality is not (IMO) a
“must have”.

The following functions are implemented/objects are exported:

Themes:

• theme_ipsum: Arial Narrow
• theme_ipsum_gs: Goldman Sans Condensed
• theme_ipsum_es: Econ Sans Condensed

• theme_ipsum_pub: Public Sans
• theme_ipsum_tw: Titilium Web
• theme_modern_rc: Roboto Condensed dark theme
• theme_ft_rc: Dark theme based on FT’s dark theme (Roboto Condensed)

Scales (that align with various themes):

  x = rep(1:50, 50),
  y = rep(1:50, each=50),

      geom_tile() +
      scale_fill_flexoki_continuous(palette = .p) +
      labs(
        x = NULL, y = NULL
      ) +
      theme_ipsum(grid="") +
      theme(legend.position = "none")
  }) |> 
  do.call(what = "wrap_plots") +
  plot_layout(ncol = 4) +

    subtitle="All 8 continuous color palettes",
    caption="Using scale_fill_flexoki_continuous()",
    theme = theme_ipsum(grid="")
  )

Bit12 Color Scales

The Bit12 color system provides a set of 12 distinct colors optimized
for data visualization.

# Discrete colors example
ggplot(mpg, aes(class, fill=class)) +
  geom_bar() +
  labs(title="Bit12 Color Palette",
       subtitle="A vibrant 12-color categorical palette",
       caption="Using scale_fill_bit12()") +
  theme_ipsum() +
  scale_fill_bit12() +
  theme(legend.position="none")

library(patchwork)
# Taking a subset of the palette for this example
names(bit12)[c(1,3,5,7,9,11)] |> 
  map(\(.p) {
    ggplot(grad_df, aes(x, y, fill=z)) +
      geom_tile() +
      scale_fill_bit12_continuous(palette = .p) +
      labs(
        x = NULL, y = NULL, title = .p
      ) +
      theme_ipsum(grid="") +
      theme(legend.position = "none")
  }) |> 
  do.call(what = "wrap_plots") +
  plot_layout(ncol = 3) +
  plot_annotation(
    title="Bit12 Continuous Color Scales",
    subtitle="Selected continuous color palettes",
