Package 'EraBrewer'

Generate a color palette

Description

Returns a vector of colors drawn from one of the palettes in EraPalettes. Supports both discrete (curated subsets) and continuous (interpolated) palettes.

Usage

era.brewer(
  palette_name,
  n,
  type = c("discrete", "continuous"),
  direction = c(1, -1),
  override_order = FALSE,
  return_hex = FALSE
)

Arguments

palette_name	Character. Name of the palette; must be one of names(EraPalettes).
n	Integer. Number of colors to return. Defaults to the full palette length.
type	One of "discrete" or "continuous". If omitted, chosen automatically: "continuous" when n exceeds the palette length, otherwise "discrete".
direction	1 for the standard order, -1 for reversed.
override_order	Logical. If TRUE, return colors in their stored order rather than the curated order-of-use for the requested n.
return_hex	Logical. If TRUE, also prints the hex codes.

Value

An object of class "palette": a character vector of hex codes with the palette name stored as an attribute.

Examples

# Discrete palette using the curated order-of-use
print(era.brewer("Lover2", n = 3))

# Continuous interpolation when n exceeds the stored palette length
print(era.brewer("Showgirl2", n = 50, type = "continuous"))

# Reverse direction
print(era.brewer("Fearless", direction = -1))

# Plug into a ggplot2 manual scale
library(ggplot2)
ggplot(iris, aes(Sepal.Length, Sepal.Width, color = Species)) +
  geom_point() +
  scale_color_manual(values = era.brewer("Lover2", n = 3))

Era Palettes

Description

A named list of color palettes inspired by Taylor Swift's eras. Each entry is a list of length two: a character vector of hex codes, and an integer vector giving the preferred order in which the colors should be drawn for discrete palettes of increasing size.

Usage

EraPalettes

Format

A named list with one entry per palette.

Value

A named list; each element is itself a list of length two: a character vector of hex codes and an integer vector giving the curated order-of-use for discrete subsets.

Examples

names(EraPalettes)
EraPalettes[["Lover2"]]

Description

S3 method for objects of class "palette". Renders the palette as a row of colored tiles labeled with the palette name.

## S3 method for class 'palette'
print(x, ...)

Arguments

x	A "palette" object as returned by era.brewer.
...	Unused.

Value

A ggplot object: a row of colored tiles labeled with the palette name. Rendered when auto-printed at the top level or when further composed with ggplot2 layers.

Examples

print(era.brewer("Lover2"))
