许多数据类的 R 调色板

Question

R中是否有可以处理许多数据类的调色板的好包？我有 16 个连续数据类。我试过 RColorBrewer 但它最多有 9 个数据类，我也试过 Rainbow() 但它对顺序数据没有吸引力。谢谢

Answer 1

经过大量实验，我想出了 25 种最容易区分的颜色。这适用于分类数据，而不是连续/顺序数据。

c25 <- c(
  "dodgerblue2", "#E31A1C", # red
  "green4",
  "#6A3D9A", # purple
  "#FF7F00", # orange
  "black", "gold1",
  "skyblue2", "#FB9A99", # lt pink
  "palegreen2",
  "#CAB2D6", # lt purple
  "#FDBF6F", # lt orange
  "gray70", "khaki2",
  "maroon", "orchid1", "deeppink1", "blue1", "steelblue4",
  "darkturquoise", "green1", "yellow4", "yellow3",
  "darkorange4", "brown"
)
pie(rep(1, 25), col = c25)
