【问题描述】:

运行以下代码:

charts.PerformanceSummary( xts(c(.05,.01,-0.1),as.POSIXct(c('2018-02-28','2018-03-29','2018-04-24'))))

我得到错误:

Error in xy.coords(x, y) : 'x' and 'y' lengths differ

    【解决方案1】:

    你的问题在这里解决了Github PerfomanceAnalytics

    第一:

    charts.PerformanceSummary(xts(c(.05,.01,-0.1), as.POSIXct(c('2018-02-28','2018-03-29','2018-04-24'), tz = "UTC")))
    

    第二:

    charts.PerformanceSummary(xts(c(.05,.01,-0.1), as.Date(c('2018-02-28','2018-03-29','2018-04-24'))))
