xy.coords（x，y）中的錯誤：'x'和'y'的長度不同圖表.PerformanceSummary R XTS

Question

運行以下代碼：

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

我收到錯誤：

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

這是sessionInfo（）的結果：

您的問題在這里解決了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'))))
