WebBTree (in fact B*Tree) is an efficient ordered key-value map. Meaning: given the key, a BTree index can quickly find a record, a BTree can be scanned in order. it's also easy to fetch all … WebNow that you can explore R’s environment tree, let’s examine how R uses it. R works closely with the environment tree to look up objects, store objects, and evaluate functions. How R does each of these tasks will depend on the current active environment. 8.2.1 The …
