Overload of operator [[]]<-.

1 2	## S3 replacement method for class 'largeList' x[[index = NULL]] <- value

`x`	A largeList object created by `getList`.
`index`	`NULL` or a numeric, character vector with length 1.
`value`	`NULL`, a vector or a list.

It behaviours the same as a normal list object. If index is not provided, the list file binding with the largeList object will be truncated and elements in value will be saved to the list file. If value is NULL, element with given index will be removed.

largeList

largelist_object <- getList("example.llo", truncate = TRUE)
largelist_object[[]] <- list("A" = 1, "B" = 2, "C" = 3)  ## assign list to the list file
largelist_object[[1]] <- NULL ## remove first element
largelist_object[["B"]] <- NULL ## remove element with name "B"
largelist_object[["C"]] <- 5 ## change value
largelist_object[[2]] <- 5 ## change value
largelist_object[[4]] <- 6 ## append 6 to 4th and NULL to 3rd position
