convert named vector to list but keep vector names

Question

I have a named vector that I want to convert to a list, as such:

a = 1:10
names(a) = letters[1:10]
as.list(a)
$a
[1] 1
$b
[1] 2
$c
[1] 3

Here, the names of each vector is now the name of the list, but I need the vectors within the list to keep their names, like this:

as.list(a)
$a
a
1
$b
b
2
$c
c
3

Any ideas? Thanks!

My question is very different. The solutions posted below (which are simple and worked) were not mentioned at all in that question. — Haloom, Oct 13 '17 at 04:14
Did you check the first and accepted solution in that question? You can easily adapt it to your requirement for this question. — Ronak Shah, Oct 13 '17 at 04:15
I reopened this question. I don't believe it's a duplicate of the linked question, and 4 out of the 5 duplicate voters were not R users. You can derive answers from other answers all over this site, but that does not mean the questions are duplicates of each other. If you can get 5 R users to agree to that duplicate then I might change my mind. — Rich Scriven, Oct 13 '17 at 23:03

You can use split().

split(a, names(a))

One option after going ahead with as.list is to the set the names of the elements with the corresponding names of original vector with Map

Map(setNames, as.list(a), names(a))
#$a
#a 
#1 

#$b
#b 
#2 

#$c
#c 
#3 

#$d
#d 
#4 

#$e
#e 
#5 

#$f
#f 
#6 

#$g
#g 
#7 

#$h
#h 
#8 

#$i
#i 
#9 

#$j
# j 
#10
