convert list of elements with repeating names to data.frame in r

Question

I have a list of elements with repeating names

l <- list(name = c("lol", "kek", "pip"),
          values = c(1,2,3),
          name = c("raph", "mike", "leo"),
          values = c(4,2,1))

How to convert it to a data frame like this in the simplest way?

data.frame(name = c("lol", "kek", "pip", "raph", "mike", "leo"),
           values = c(1,2,3,4,2,1))

  name values
1  lol      1
2  kek      2
3  pip      3
4 raph      4
5 mike      2
6  leo      1

Answer 1

in Base R you can do:

unstack(stack(l))
  name values
1  lol      1
2  kek      2
3  pip      3
4 raph      4
5 mike      2
6  leo      1

To maintain the underlying data type, use:

type.convert(unstack(stack(l)), as.is =TRUE)
  name values
1  lol      1
2  kek      2
3  pip      3
4 raph      4
5 mike      2
6  leo      1
