string - 连接 R 中的列表元素

Question

我有一个列表，其中每个元素都包含字符串，如下所示:

[[1]] 
 [1] 
 "diane"    "bradbury"

[[2]] 
 [1] "diane"    "bradbury"

 [[3]] 
  [1] "derek" "legg"

我需要获得的是这样的一列数据框:

"diane bradbury" 
"diane bradbury" 
"derek legg"

您能指点一下吗？谢谢。

Answer 1

只需将paste与sapply一起使用:

myList <- list(c("A", "B"), c("C", "D"), c("E", "F"))

myList
# [[1]]
# [1] "A" "B"
# 
# [[2]]
# [1] "C" "D"
# 
# [[3]]
# [1] "E" "F"

sapply(myList, paste, collapse = " ")
# [1] "A B" "C D" "E F"
