使用 write_xlsx 保存列表的每个 data.frame

Saving each data.frame of list with write_xlsx

想要将列表的每个 data.frame 单独保存为具有 write_xlsx 功能的 Excel Workbook。能够将列表的每个 data.frame 分别保存为 .RData 但不能保存为 Excel Workbook。有什么想法。

library(tidyverse)
library(writexl)

df1 <- data.frame(X = 1:3)
df2 <- data.frame(X = 5:6)

ls1 <-
  list(df1, df2) %>% 
  set_names(c("df1", "df2"))
ls1
#> $df1
#>   X
#> 1 1
#> 2 2
#> 3 3
#> 
#> $df2
#>   X
#> 1 5
#> 2 6


map(.x = names(ls1), .f = function(x1){
  assign(x = x1, ls1[[x1]])
  save(list = x1, file = paste0(x1, ".RData"))
  })
#> [[1]]
#> NULL
#> 
#> [[2]]
#> NULL


map(.x = names(ls1), .f = function(x1){
  assign(x = x1, ls1[[x1]])
  write_xlsx(x = x1, path = paste0(x1, ".xlsx"))
  })
#> Error in write_xlsx(x = x1, path = paste0(x1, ".xlsx")): Argument x must be a data frame or list of data frames

使用 openxlsx R 包中的 write.xlsx 函数的以下 R 代码可以工作并生成具有多个工作表的单个 Workbook

write.xlsx(x = ls1, file = "ls1.xlsx")

但是,我要求将每个 data.frame 保存在单独的 Workbook 中,并尝试了 openxlsx R 包中的 write.xlsx 函数,但它产生了错误的输出:

map(.x = names(ls1), .f = function(x1){
      assign(x = x1, ls1[[x1]])
      write.xlsx(x = x1, path = paste0(x1, ".xlsx"))
      })

做:

library(openxlsx)
lapply(1:length(ls1), function(x) write.xlsx(ls1[[x]], file = paste0(names(ls1)[x], '.xlsx')))

相同的代码与 map 完全相同:

library(purrr)
map(.x = 1:length(ls1),
    .f = function(x) write.xlsx(ls1[[x]], file = paste0(names(ls1)[x], '.xlsx')))
