我正在尝试将xts对象列表写入同一xlsx Excel文件的多个工作表中。但是，我无法将xts对象的日期戳（即索引/行名）打印到电子表格中。
样本的Dput输出：

我尝试过：
outputFileName <- "Equity.xlsx"
wb <- tryCatch(loadWorkbook(outputFileName), error=function(e){createWorkbook()})
outputName <- "Price"
ifelse(outputName %in% sheets(wb),paste(outputName, "sheet exists", sep = " "),addWorksheet(wb, sheetName = outputName, gridLines = FALSE))
其次：
output <- cbind(Data = rownames(tempX), tempX)
writeData(wb, sheet = outputName, output, rowNames = TRUE, keepNA = TRUE)
或
output <- tempX
writeData(wb, sheet = sheetName, output, rowNames = TRUE, keepNA = TRUE)
两者均未设法打印时间戳。 index(output)和dimnames.xts[[1]]也会产生NULL输出。
有什么想法吗？
library(zoo)
tempX <- fortify.zoo(tempX)
