英文:
Writing multiple data frames from a list into excel, split 1 factor across different sheets and order by another factor
问题
这是一些数据。
a <- rnorm(1000, 1, 1)b <- rep(letters[1:10], each = 100)d <- rep(c("x", "y", "z", "q"), 250)abd <- cbind.data.frame(a, b, d)
我想根据一个因子（在这种情况下是 "b"）将这个数据框拆分成数据框列表，然后将这个数据框列表以一种方式写入Excel，其中每个因子 "b" 将被放在一个新的工作表上，而因子 "d" 将按指定顺序排序（例如，首先是 x，然后是 y，然后是 z，然后是 q）。
首先，我尝试根据因子拆分：
abdlist <- split(abd, abd$b)abdlist[1]
这部分目前看起来很好，但我希望在将列表写入Excel时指定因子 "d" 的顺序。
使用以下库来实现这个目标：
library(dplyr)library(writexl)abdlist %>% write_xlsx(path = "path.xlsx")
这将把数据写入Excel文件 "path.xlsx" 中，并根据因子 "b" 创建新的工作表，并按指定的顺序排列因子 "d"。
英文:
Here is some data.
a<-rnorm(1000, 1,1)b<-rep(letters[1:10], each = 100)d<-rep(c("x","y","z","q"),250)abd<-cbind.data.frame(a,b,d)
I would like to split this data frame into list of data frames based on a factor (b in this case) and than write this list of data frame into excel in a way that each factor "b" will be placed on a new sheet and factor "d" will be ordered in a specified way (e.g. first comes x, than y, than z, than q).
I first tried to split by factor:
abdlist<-split(abd, abd$b)abdlist[1]
This looks fine for now, I would like to specify the order of factor "d" when I am writing the list to excel.
library(dplyr)library(writexl)abdlist %>%:write_xlsx(path = "path.xlsx")

以下是翻译后的代码部分：
library(purrr)library(dplyr)library(openxlsx)wb <- createWorkbook()abdlist %>%map(~ .x %>%mutate(d = factor(d, levels = c("x", "y", "z", "q")))%>%arrange(d)) %>%iwalk(function(.data, sheet_name) {addWorksheet(wb = wb, sheetName = sheet_name)writeData(wb = wb, x = .data, sheet = sheet_name)})saveWorkbook(wb = wb, file = "text.xlsx", overwrite = TRUE)
英文:
You could use purrr for this:
library(purrr)library(dplyr)library(openxlsx)wb <- createWorkbook()abdlist |>map(~.x |>mutate(d = factor(d, levels = c("x","y","z","q"))) |>arrange(d)) |>iwalk(function(.data, sheet_name) {addWorksheet(wb = wb, sheetName = sheet_name)writeData(wb = wb, x = .data, sheet = sheet_name)})saveWorkbook(wb = wb, file = "text.xlsx", overwrite = TRUE)
