You can use [[<- with a character argument for the key
> myList<-list()
> i<-"10"
> myList[[i]] <- 11
> myList
$`10`
[1] 11
If you use an integer argument, as in,
myList[[10]] <- 11
then 11 becomes the 10'th element of myList, not the
element named '10'.
myList[[i]] <- NULL
will remove the element.
