William Morris的方案按照世界名画的配色进行选取,特别适合在sci文章中进行展示。
安装

所有的颜色都用magick和imager包进行提取,下面是William Morris最著名的6个方案:
Strawberry Thief (1883)

例子
示例数据集中,iris在R中应用较多(correlation,regression,classification),titanic在Python中应用更为广泛。下面用另一个数据集penguins:
penguins和penguins_raw都包含在palmerpenguins包。是由Dr. Kristen Gorman收集的 the Palmer Station, Antarctica LTER企鹅数据信息。

#loadfonts(device = "win") #应用新的字体

主要包含8列企鹅的信息:
-
种类(species)
-
所在岛屿(island)
-
喙的长度和厚度(bill_length,bill_depth)
-
翅膀的长度(flipper_length)
-
体重(mass)
-
性别(sex)
-
纳入观察的年份(year)
企鹅特征
penguins %>%
ggplot(aes(flipper_length_mm,body_mass_g,shape=species,colour=species))+
geom_point(size=3)+
