R:在参数中使用求值问题编写\u xlsx

而不是 i = df 必须命名列表元素。对于你的循环,这意味着:

file_output = "C:/test/test.xlsx"
for(i in 1:2){
  df <- iris[i,]
  out <- list(df)
  names(out) <- i
  write_xlsx(out, file_output)
}

但是,这将导致每个数据框,自 write_xlsx

file_output = "C:/test/test.xlsx"
vars <- 1:2
out <- vector(mode = "list", length = length(vars))
for(i in vars){ # if you use variable names in vars, use seq_along(vars) instead of vars
  out[[i]] <- iris[i,]
}
names(out) <- vars
write_xlsx(out, file_output)

既然我不认为在这里使用循环有什么好处,我甚至建议使用 map 从 purrr lapply :

file_output = "C:/test/test.xlsx"
vars <- 1:2
out <- map(vars, ~ iris[.x,])
names(out) <- vars
write_xlsx(out, file_output)

只是使用 names() 上 list 对象 as.character() 为了给床单命名。

l <- lapply(1:2, function(i) iris[i, ]) #creates separated df for each row
names(l) <- as.character(1:2) # sets the names of each element in the list
# these will be the sheets name


file="path_to_file.xlsx" # path to file name
library(writexl)

write_xlsx(l, file)
