t2m ggplot2 theme

A white-background ggplot2 theme based on the Urban Institute style, with gray horizontal grid lines and a clean, minimal aesthetic. Designed to pair with viridis, inferno, grayscale, or solaris color palettes (set via set_theme).

Usage

theme_t2m(
  base_size = 12,
  base_family = "sans",
  base_line_size = 0.5,
  base_rect_size = 0.5,
  panel_spacing = 6,
  network = NULL,
  medium = c("screen", "print")
)

Arguments

base_size: Numeric. Base font size in points (default 12).
base_family: Character. Base font family (default "sans").
base_line_size: Numeric. Base line size for theme elements (default 0.5).
base_rect_size: Numeric. Base rectangle border size for theme elements (default 0.5).
panel_spacing: Numeric. Spacing between facet panels in points (default 6).
network: Logical or NULL (default). If NULL, ggraph plots are auto-detected at plot-add time and network mode is applied automatically. Pass TRUE to force network mode (no axes/grid) or FALSE to force standard mode regardless of plot type.
medium: Character. Output medium: "screen" (default) for presentations and PDF viewing, or "print" for physical printing with heavier lines and darker text.

Value

When network = NULL (default), an object of class "theme_text2map_autodetect" that resolves at + time. When network is explicitly TRUE or FALSE, a plain ggplot2 theme object.

Details

When added to a plot with +, theme_t2m() auto-detects whether the plot is a ggraph network visualization and removes axes and grid lines accordingly. Pass network = TRUE or network = FALSE to override auto-detection.

Note

theme_t2m() is based on the Urban Institute theme (https://urban-institute.graphics/).

Examples

if (FALSE) { # \dontrun{
library(ggplot2)

# Basic usage -- auto-detects plot type
ggplot(mtcars, aes(wt, mpg)) +
  geom_point() +
  theme_t2m()

# Print-optimized with heavier lines
ggplot(mtcars, aes(wt, mpg, color = factor(cyl))) +
  geom_point(size = 3) +
  theme_t2m(medium = "print")
} # }
