  "Description": "Fast implementation of data structures, including a\nkey-value store, stack, and queue. Environments are commonly\nused as key-value stores in R, but every time a new key is\nused, it is added to R's global symbol table, causing a small\namount of memory leakage. This can be problematic in cases\nwhere many different keys are used. Fastmap avoids this memory\nleak issue by implementing the map using data structures in\nC++.",
