RColorBrewer 16進数コードまとめ

色の16進数表記をいちいち出すのがめんどうなので、メモ

の前に

RColor Brewerでよく使うコマンド

library(RColorBrewer)

#全てのカラーパレットの表示
display.brewer.all(n = NULL, 
                   type = "all", 
                   select = NULL,
                   colorblindFriendly = FALSE)
##これだけでも良い
display.brewer.all()

#１つのカラーパレットの表示
display.brewer.pal(n = 8, name = 'Dark2')

#色の16進数表記を抽出
##nは3以上でないと（なぜか）エラーが出る
brewer.pal(n = ４, name = "Dark2")

##output
##[1] "#1B9E77" "#D95F02" "#7570B3" "#E7298A"
