Hi R users,
I have a list:
x
$A
[1] "a" "b" "c"
$B
[1] "b" "c"
$C
[1] "c"
I want to convert it to a lowercase-to-uppercase list like this:
y
$a
[1] "A"
$b
[1] "A" "B"
$c
[1] "A" "B" "C"
In a word, I want to reverse the list names and the elements under
each list name. Is there any quick way to do that? Thanks
The obvious way would be:
names(lll) <- to.upper(names(lll)
lll <- lapply(lll, to.lower)
(If you had offered code that would construct the list, I would have
tested it.)
