如何在formattable（）包R中用小数点分隔符逗号替换小数点分隔符点？

Question

我有一个数据库，我使用formattable()包显示了这些数据。 但是在我的国家，我们使用逗号作为小数点分隔符，这与 R 使用的标准点不同。

如果可能，我如何更简单地更改它，使用%>%运算符

aa2<-read.table(text="Ano   v   u   a   p   ur  h   e   t

Answer 1

您可以通过设置decimal.mark = ","来实现您想要的结果：

library(formattable)
library(dplyr)

aa2 <- aa2  %>%
  mutate(across(v:t, ~ formattable::comma(., digits = 2, decimal.mark = ",", big.mark = "")))

formattable::formattable(aa2, list(
  'v' = color_tile("#00cccc","#0066cc"),
  'u' = color_tile("#00cccc","#0066cc"),
  'a' = color_tile("#00cccc","#0066cc"),
  'p' = color_tile("#00cccc","#0066cc"),
  'ur' = color_tile("#00cccc","#0066cc"),
  'h' = color_tile("#00cccc","#0066cc"),
  'e'= color_tile("#00cccc","#0066cc")
))
