Insper Custom ggplot2 Theme

Source: R/theme_insper.R
theme_insper.Rd

A ggplot2 theme built on Insper's brand colors and typography, with arguments for grid lines, borders, and title alignment.

Usage

theme_insper(
  base_size = 12,
  font_title = "Georgia",
  font_text = "Inter",
  grid = TRUE,
  border = "none",
  align = "panel",
  ...
)

Arguments

base_size

Numeric. Base font size in points. Default is 12. All other text sizes are relative to this value.

font_title

Character. Font family for the plot title. Default is "Georgia", the substitute for Insper's proprietary GT Ultra. Falls back to the system "serif" family if Georgia is unavailable.

font_text

Character. Font family for all other text (subtitle, axis labels, legend, caption). Default is "Inter", which ships with the package. Falls back to "Arial", then to the system "sans" family.

grid

Logical. If TRUE (default), draws light gray major grid lines. If FALSE, removes all grid lines. Minor grid lines are always removed.

border

Character. Plot border style, one of the options below.

  • "none" (default): no border or axis lines.

  • "half": axis lines with ticks, but no full border.

  • "closed": a full rectangle around the panel.

align

Character. Alignment of the title, subtitle, and caption, one of the options below.

  • "panel" (default): align to the plot panel.

  • "plot": align to the whole plot, including margins.

...

Additional arguments passed to ggplot2::theme_minimal().

Value

A ggplot2 theme object, added to a plot with +.

Details

The theme sets a white plot background, places a horizontal legend at the top with a bold title, removes minor grid lines, and draws remaining elements in Insper brand grays.

Fonts

Titles use Georgia and all other text uses Inter. Inter is bundled with the package and registered automatically on load. Georgia is a system font that stands in for Insper's proprietary GT Ultra. If Georgia is missing, titles fall back to the system "serif" family; if Inter is missing, text falls back to Arial and then to the system "sans" family.
