[R] Structuring Inventory in R

[Alex Naverniak]

Thank you.
The problem is that I need multiple same size data structures for each item
name. For example: Unique item name -"Table" has several (Lets say 5)
subitems of 3 items in each("Size", "Price", "Qty"); Another item "Chair"
has 4 subitems of the same structure (3 positions in each), etc. That list
of furniture unique items may have indefinite number of triple subitems. I
need to hace access to each position of subitem like [[1]][[3]][[2]]. I
also need to dynamically add subitems and furniture items. The total size
of furniture inventory is not known at the beginning. I hope it makes
sense. Thank you.
