tlist: An opinionated way to construct (tree-like) lists

In strboul/mmy: Custom miscellaneous R functions

Description

An opinionated way to construct (tree-like) lists

Usage

tlist()

Details

• There're no list names in tlist, only indices.

• The list is flat. The nodes staying at the same level are not wrapped in another list, rather a new node has been created.

• 'tlist's are designed to be used in small, not long stuctures. The semantics doesn't allow to go super deep down.

________________________________________________________
(1)...........A..........B..............C...............
_____________[1]________[2]____________[3]______________
............/.|.\........|......../...|...|...\.........
(2)........A..B..C.......A.......A....B...C....D........
_____________[1]________[2]____________[3]______________
........../.\....|..../.|.|.\........|....|.../.|.\.....
(3)......A...B...A...A..B.C..D.......A....A..A..B..C....
_________[1]____[2]_____[3]_________[4]__[5]___[6]______
(...)

As seen in the graph above,

• The indexes surrounded by parentheses appearing in each line indicate levels, e.g. (1).

• The indexes placed in the bar appearing under the letters indicate nodes, e.g. [5].

Examples

## Not run: 
## Instantiate a tlist to keep fruit data:
fruits <- tlist()
fruits$append("apple", 1, 1)
## Append a child
fruits$append("seed", 1, 3)
## Append siblings:
fruits$append(c("orange", "watermelon"), 1)
## Get the main list:
fruits$main()

## End(Not run)
