Question

我正在尝试使用PerformanceAnalytics::charts.PerformanceSummary()

绘制日内数据

但是我收到以下错误消息：

charts.PerformanceSummary(e[,1:10])

Error in as.POSIXlt.POSIXct(.POSIXct(.index(x)), tz = indexTZ(x)) : 
      invalid 'tz' value

charts.PerformanceSummary似乎只收集每日数据而不是当日数据？

有人可以为此提出解决方案吗？

 e <- structure(c(0, 0, 0, 0, 0, 0, 0, 0, 0.000369303493611195, 0, 
0, 0.000590667454223315, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,

问题是POSIXlt索引。您应该将其转换为POSIXct，这最容易通过创建新的xts对象来完成。请尝试以下命令。

e <- xts(coredata(e), as.POSIXct(index(e)))
PerformanceAnalytics::charts.PerformanceSummary(e[,1:10])

在绘制第一个图之后，图表会引发示例数据错误：

Error in segments(xlim[1], y_grid_lines(ylim), xlim[2], y_grid_lines(ylim),  : 
  cannot mix zero-length and non-zero-length coordinates

但这可能是因为没有足够的观察结果。如果它对您的实际数据不起作用，请告诉我，我会进一步调查。

charts.PerformanceSummary（）不适用于日内数据
