Combining the rows of a dataframe where each row is a df itself

Question

I have an object with each row being a dataframe or list itself like this:

[[1]]
1: a b c d
   1 1 2 4

[[2]]
1: a b c d
   4 3 6 2

[[3]]
1: a b c d 
   1 2 2 1

How can I transform this to a dataframe like below?

a b c d 
1 1 2 4
4 3 6 2
1 2 2 1

Answer 1

We can use rbindlist

library(data.table)
rbindlist(lst1)

---

Or with rbind and do.call in base R

do.call(rbind, lst1)
