如何从闪亮的数据表中删除时区?

How to remove timezone from datatable in Shiny?

目前,当我将 PerformanceAnalytics 包的一些输出包装到 Shiny 的 datatable(DT 包)中时,日期得到 T:00:00:00Z 在浏览器中附加到它们。

例如,2015-01-31T00:00:00Z 并且只需要 2015-01-31.

如何防止这种情况发生并只显示 yyyy-mm-dd?数据表中是否有我不知道的设置?

library(PerformanceAnalytics)
library(DT)
library(xts)

DT::datatable(table.Drawdowns(rets))

TABLE 看起来像什么

您可以使用格式化功能,例如:

DT::datatable(table.Drawdowns(rets)) %>% formatDate(c(1,2,3), method = 'toDateString')
