R list of lists to data.frame

Question

I\'ve got a list of lists, call it listHolder, which has length 5.

Every element in listHolder is a list of numeric data, with 160 or so e

Answer 1

I think this is easier than the previous solutions:

mydf = data.frame(x1 = c('a', 'b', 'c'))
mylist = list(c(4, 5), c(4, 5), c(4, 5))
mydf$x2 = mylist
print(mydf)
  x1   x2
1  a 4, 5
2  b 4, 5
3  c 4, 5
