text2map.theme: Theme for ggplot2

This is an R Package for customizing the ggplot2 aesthetics. See also text2map.

Installation and Usage

library(remotes)
install_gitlab("culturalcartography/text2map.theme")

# Basic setup (uses viridis colors)
text2map.theme::set_theme()

Themes

text2map.theme provides two ggplot2 themes: the default white background theme and the solaris theme with a warm cream palette.

Global Palette Options

text2map.theme includes four palette options:

# Default: Perceptually uniform (best for digital/accessibility)
text2map.theme::set_theme(palette = "viridis")

# Inferno: Dark purple to bright yellow, perceptually uniform
text2map.theme::set_theme(palette = "inferno")

# Grayscale: Best for textbook printing
text2map.theme::set_theme(palette = "grayscale")

# Solaris: Custom purple-to-gold warm palette
text2map.theme::set_theme(palette = "solaris")

Note: This setting applies globally to all subsequent ggplot plots.

Font Configuration

The package bundles Open Sans and Lato fonts for offline use. To enable these, set set_font = TRUE.

# Use Lato instead of default Open Sans
text2map.theme::set_theme(set_font = TRUE, base_family = "Lato")

# Use 'extrafont' for legacy support (showtext is default/recommended)
text2map.theme::set_theme(set_font = TRUE, font_method = "extrafont")

Rendering Recommendation: We recommend font_method = "showtext" (default) for best cross-platform rendering.
