r - 如何将列表输出到R中的文件

Question

假设有一个带有作者的书籍列表，在将数据读入列表“LS”后，我尝试将其输入到文件中，输出为

> write.table(LS, "output.txt")
Error in data.frame(..., title = NULL,  : 
  arguments imply differing number of rows: 1, 0

> write(LS, "output.txt")
Error in cat(list(...), file, sep, fill, labels, append) : 
  argument 1 (type 'list') cannot be handled by 'cat'

我能够使用 dput 但我希望数据格式正确(整个文件中没有重复关键字的冗余)。有什么建议？
谢谢

更新
dput(头(LS，2))

list(structure(list( title = "Book 1", 
authors = list(structure(c("Pooja", "Garg"),
 .Names = c("forename","surname")), 
structure(c("Renu", "Rastogi"), 
.Names = c("forename","surname")))),
 .Names = c("title", "authors")), 

structure(list( title = "Book 2", 
 authors = list(structure(c("Barry", "Smit"), .Names = c("forename", 
    "surname")), structure(c("Tom", "Johnston"), .Names = c("forename", 
    "surname")))), .Names = c("title", "authors")))

Answer 1

您可以先将列表转换为数据框:

LS.df = as.data.frame(do.call(rbind, LS))

或者

LS.df = as.data.frame(do.call(cbind, LS))

然后你可以简单地用 write.csv 或 write.table 保存 LS.df
