【问题描述】：

我想创建一些用于 ggplot 和 facet wrap 的 bin。我希望将它们格式化为货币，并希望防止它们以科学记数法显示。

这是垃圾箱：

xbin <- cut(x, breaks = c(0, 100, 1000, 10000))
> table(xbin)
xbin
      (0,100]   (100,1e+03] (1e+03,1e+04] 
          149           465           210

我希望 bin 标签是货币（美元）并且也以常规形式显示，而不是科学的，例如$0:100、$100:1,000 等

我该怎么做？

【问题讨论】：

cut 有标签参数。

您可以将这些中断分配为附加变量，并使类成为“因素”。那么您应该可以将该变量用作 ggplot 2 中的 x 变量。您也可以在 ggplot 中分配箱，但有时我也喜欢在我的数据框中使用因子变量。

【参考方案1】：

使用标签：

xbin <- cut(x, 
            breaks = c(0, 100, 1000, 10000),
            labels = c("$0:100", "$100:1,000", "$1000:10,000"))
table(xbin)
# $0:100   $100:1,000 $1000:10,000 
#    149          465          210 

或者使用 dig.lab 到avoid scientific notation:

xbin <- cut(x, 
            breaks = c(0, 100, 1000, 10000),
            dig.lab = 5)
table(xbin)
# xbin
# (0,100]   (100,1000] (1000,10000] 
#    149          465          210 

【参考方案2】：

使用cutr，您可以定义自定义标签功能：

# devtools::install_github("moodymudskipper/cutr")
library(cutr)

xbin <- smart_cut(
  x, c(0, 100, 1000, 10000), expand = FALSE,
  labels = ~paste0("$",format(.y[1], big.mark=","),":", format(.y[2],big.mark=",")))
table(xbin)
# xbin
#       $0:100    $100:1,000 $1,000:10,000
#          318           465           210 

在标签函数内部，.y 包含两个边界，而.x 将包含它们之间的数据点。

您可以分开定义函数以便重用或提高可读性：

label_fun <- function(.x,.y) paste0("$",format(.y[1], big.mark=","),":", format(.y[2],big.mark=","))
xbin <- smart_cut(x, c(0, 100, 1000, 10000), expand = FALSE, labels = label_fun)
table(xbin)
# xbin
#       $0:100    $100:1,000 $1,000:10,000
#          318           465           210
