Transpose a List of Lists

Question

I have a list which contains list entries, and I need to transpose the structure. The original structure is rectangular, but the names in the sub-lists do not match.

Answer 1

The purrr package now makes this process really easy:

library(purrr)

before %>% transpose()

## $x
## $x$a
##   a x
## 1 1 2
## 
## $x$b
##   b w
## 1 5 6
## 
## 
## $y
## $y$a
##   a y
## 1 3 4
## 
## $y$b
##   b z
## 1 7 8
