r - 将列表转换为数据框(Convert a list to a data frame)

Question

I have a nested list of data.

(我有一个嵌套的数据列表。)

Its length is 132 and each item is a list of length 20. Is there a quick way to convert this structure into a data frame that has 132 rows and 20 columns of data?

(它的长度是132，每个项目都是一个长度为20的列表。是否有一种快速的方法将这种结构转换为具有132行和20列数据的数据帧？)

Here is some sample data to work with:

(以下是一些示例数据：)

l <- replicate(
  132,
  list(sample(letters, 20)),
  simplify = FALSE
)

Answer 1

With rbind

(与rbind)

do.call(rbind.data.frame, your_list)

Edit: Previous version return data.frame of list 's instead of vectors (as @IanSudbery pointed out in comments).

(编辑：以前版本的回报data.frame的list的替代载体（如@IanSudbery在评论中指出）。)
