R 中的华夫饼图：图例文本仅由 "A"、"B"、"C" 组成；如何改变？

Question

我有这个数据框 DF:

|total | n  |
|------|----|
| 0    | 19 |
| 1    | 16 |
| 2    | 23 |
| 3    | 31 |
| 4    | 20 |
| 5    | 95 |

... 或者，使其可重现：

> dput(DF)
structure(list(total = c(0, 1, 2, 3, 4, 5), n = c(19L, 16L, 23L, 
31L, 20L, 95L)), row.names = c(NA, 6L), class = "data.frame")

现在，如果我用它制作华夫饼图表：

library(waffle)
waffle(DF$n, rows=6, size=0.6, 
       colors=c("#EAECEC", "#DFE0E2", "#B3B6BC", "#888D96", "#4E5656", 
                "#0A0B0B"), 
       #title="Legal Databases", 
       xlab="1 square == 1 country")

...我得到一个由“A”、“B”、“C”等组成的图例文本：

如何更改图例文本？我希望它显示为“分数：0”、“分数：1”等，直到“分数：5”而不是“A”、“B”、“C”等

我尝试使用中的 names() 解决方案，但没有成功。

Answer 1

根据waffle

If the vector is not named or only partially named, capital letters will be used instead.

因此，我们可以创建一个命名向量并传递

library(waffle)
v1 <- setNames(DF$n, paste0("Score: ", seq_along(DF$n)-1))
waffle(v1, rows=6, size=0.6, 
       colors=c("#EAECEC", "#DFE0E2", "#B3B6BC", "#888D96", "#4E5656", 
                 "#0A0B0B"), 
        #title="Legal Databases", 
        xlab="1 square == 1 country")

-输出

与 akrun 类似的解决方案！在文档 https://cran.r-project.org/web/packages/waffle/waffle.pdf 中有参数 parts = 用于图表的命名向量值：

library(waffle)
parts=c(DF$n)
names(parts) = paste0("Score: ", DF$total)
waffle(parts, rows=6, size=0.6, 
       colors=c("#EAECEC", "#DFE0E2", "#B3B6BC", "#888D96", "#4E5656", 
                "#0A0B0B"), 
       #title="Legal Databases", 
       xlab="1 square == 1 country")
