transpose nested list

Question

I have a list structure which represents a table being handed to me like this

> l = list(list(1, 4), list(2, 5), list(3, 6))
> str(l)
List of 3
 $ :Lis         


        

Answer 1

We can use

library(tidyverse)
r1 <- l %>% 
        transpose %>%
        map(unlist)
identical(r1, unname(lt))
#[1] TRUE
