R boxplot这个手册怎么填错了

Question

我想用不同的方式为箱线图变量着色。我查看了 here 并尝试了以下内容，但绘图框都是标准的白色（我在类型中有 6 个因子）。我应该改变什么？

library(ggplot2)
ggplot(PGcounts, aes(Type, Word)) + 
            geom_boxplot() + 
            coord_trans(y = "log10") +
            scale_fill_manual(values = c("white","white","white","red","blue","white"))

Answer 1

需要改变的是

geom_boxplot() +

到

geom_boxplot(fill = c("white","white","white","red","blue","white")) +

并删除

scale_fill_manual(values = c("white","white","white","red","blue","white"))

Answer 2

您也可以将原始代码中的 geom_boxplot() 更改为 geom_boxplot(aes(fill=Type))。

例如：

ggplot(PGcounts, aes(Type, Word)) + 
        geom_boxplot(aes(fill=Type)) + 
        coord_trans(y = "log10") +
        scale_fill_manual(values = c("white","white","white","red","blue","white"))
