Question

我正在尝试使用R＆＃39; quantmod＆＃39;同时为很多公司从谷歌财务获取财务信息。我在列表中获得了令人满意的结果，但我想将其导出到excel文件中。每个列表成员使用不同的电子表格，所述表格的名称是列表中的名称。到目前为止，我有这个代码和输出：

library(quantmod)
library(dplyr)
library(tidyr)
symbols <- stockSymbols()[,1:2]
allfunc<-function(y) sapply(fin1, function(x) x$IS$A[y, ],USE.NAMES = TRUE)*10^6
s <- c("AAPL","GOOG","IBM","GS","AMZN","GE")
want<-c("Total Revenue","Operating Income")
fin1 <- lapply(s, getFinancials, auto.assign=FALSE,names=s)
names(fin1)<-s
all<- lapply(want,allfunc)
ss<-sapply(want,allfunc)
names(all)<-want
all

和输出＆＃39;全部＆＃39;是：

$`Total Revenue`

我想要两张纸＆＃34;收入＆＃34;，＆＃34;营业收入＆＃34;在xlsx中同时保持rownames和columnnames。但我无法找到一种方法来列表。请帮忙

Answer 1

这样的事情：

library(xlsx)

wb = createWorkbook()  # Create an Excel workbook object

lapply(names(all), function(s) {
  sht = createSheet(wb, s)        # Add a sheet to the workbook using the name of the list element we want to save
  addDataFrame(all[[s]], sht)     # Add the list element (i.e., the data frame) to the current worksheet
}

saveWorkbook(wb, "my_workbook.xlsx")  # Save the workbook as a Excel file

将列表从R导出到Excel，同时保留列表名称和子列表名称
