你如何将列表转换为R中的数据框

Question

I have list as below and like to convert it to a data frame, any ideas?

x

str(x) looks like this:

List of 2
 $ :List of 8
  ..$ :'data.frame':    1 obs. of  5 variables:
  .. ..$ DATE_TIME    : chr "2013-MAY-30 09:17 AM"
  .. ..$ SITE         : chr "Home Page - User Time]"

Answer 1

这看起来像是data.frames的双嵌套列表，所以请尝试：

do.call(rbind,unlist(x,FALSE))
